That would be I-95, which is 1,917 miles long and traverses 15 states, from Maine all the way to Miami, Florida. Keep in mind that it moves through the D.C. congestion, Philadelphia, New York and Boston.
I know that LA has an awful interstate system, I've experienced that mess numerous times. But all the traffic on the east coast, and especially the New York area takes the title.
那指的是I-95公路，它全长1917英里，横跨15个州，从缅因州一直延伸到佛罗里达州的迈阿密。需注意，这条公路会经过华盛顿特区的拥堵路段，以及费城、纽约和波士顿等大城市。
我知道洛杉矶的州际公路系统状况不佳，我多次亲身体验过那里的混乱。但东海岸的交通状况，尤其是纽约地区，更是糟糕至极。

I am sure Californians will disagree, but I believe it is I 95. Interstate I 95 runs from Maine’s Tourist track through Boston, through New York City, Newark New Jersey, Philadelphia Pa, Baltimore MD, through Washington DC, and all the way down through Florida. You can not begin to imagine how heavily these routes are traveled by cars and trucks.
我确信加州人可能有不同看法，但我认为I-95公路是最繁忙的。I-95公路从缅因州的旅游胜地开始，经过波士顿、纽约市、新泽西州的纽瓦克、宾夕法尼亚州的费城、马里兰州的巴尔的摩，再穿过华盛顿特区，一直延伸到佛罗里达州。你无法想象这些路线上的车流量和卡车流量有多密集。

I would GUESS it is IH-10, which runs from Los Angeles thru New Mexico and then the ENTIRE WIDTH of Texas and across the southern Gulf states all the way to Miami Florida. I’ve always thought it would be cool to hitch-hike from LA to Miami on I-10,
but it would not be a 1 day trip. You’d have to figure out sleeping arrangements along the way, food, washing clothes, etc. There is a LOT of traffic on IH-10 everywhere along the way. Also high traffic is the I-5 (north south) in California. It runs along the coast, I forget the end-point cities, but it’s nearly the whole length of California.
我猜想是IH-10公路，它起始于洛杉矶，穿过新墨西哥州，接着横跨德克萨斯州全境，再通过南部的墨西哥湾沿岸各州，一直延伸到佛罗里达州的迈阿密。我一直觉得从洛杉矶搭便车到迈阿密的I-10公路会是一次很酷的旅行，但这肯定不是一天就能完成的旅程。你需要在路上解决住宿、食物、洗衣服等问题。IH-10公路沿途各处的车流量都非常大。另外，加利福尼亚州的I-5公路（南北向）交通也很繁忙，它沿着海岸线延伸，我不太记得具体的起点和终点城市，但它几乎贯穿了整个加州。

According to the U.S. Department of Transportation's Federal Highway Administration (FHWA), traffic data from 2011 showed the 405 Freeway — from Interstate 5 down to Long Beach — serves an estimated 379,000 vehicles per day, making it the busiest interstate in America.
根据美国交通部联邦公路管理局（FHWA）2011年的交通数据显示，405号高速公路——从I-5到长滩——每天的车流量估计达到379,000辆，这使其成为美国最繁忙的州际公路。

What is the most traveled interstate in the US?
In my many, trips here on the west coast, my guess that interstate 5 would fit this. Starting at the Canada border, south thru Washington state 300 miles, then continues south thru Oregon 300+ miles, still moving south thru California 780 miles to the Mexican border.
lots to see in the great northwest.
美国哪条州际公路交通量最大？
在我在西海岸的多次旅行中，我猜想5号州际公路应该是最繁忙的。它从加拿大边境起始，向南穿过华盛顿州大约300英里，然后继续延伸，经过俄勒冈州300多英里，再穿越加利福尼亚州780英里直至墨西哥边境。
西北地区有很多壮丽的景观值得一看。

I would have to agree with Bion Michael Shelden. Though certain shorter stretches of interstates might be busier, if you take in the full length of I-95 it would be hard to compete. I-95 is the main highway along the eastern coast and it serves multiple cities traffic where I-405 is a relatively short span that serves only one city. I’ve traveled over most of the interstate system at one time or another and I’ve never seen as much traffic as the whole of I-95.
虽然某些州际公路的较短区段可能更繁忙，但如果从整体长度来看，I-95公路很难被超越。I-95是沿着东海岸的主要干道，它承载了多个城市的交通流量；相比之下，405号州际公路则是较短的一段，仅服务于一个城市。我曾驾车经过大部分州际公路系统，但从未见过像I-95那样繁忙的车流。

The most heavily traveled area of the Interstate Highway system is the 405 Freeway in Seal Beach, California, with a 2002 estimate of 377.000 vehicles a day.
405号高速公路在加利福尼亚州海豹滩路段是州际公路系统中交通最密集的区域，2002年的数据显示，每天大约有377,000辆车通过。

Used to be interstate I-5 and I-405. LA was certainly a busy spot. During the pandemic nothing is as it was. But in recent years the I-95 would have been well traveled as well.
以前交通最繁忙的是I-5和I-405州际公路。洛杉矶无疑是个交通繁忙的地方。疫情期间，一切都变了。但在过去几年里，I-95州际公路的交通量也相当大。

I-95 runs from Miami to Maine, I think, but I don’t know if that is the most traveled. I-405 runs from Washington to Los Angeles, so it may be more traveled.
I-95州际公路从迈阿密一直延伸到缅因州，我不确定它是否是最繁忙的。I-405州际公路从华盛顿延伸到洛杉矶，所以它可能更繁忙。

Well you have several interstate in America, you have interstate 80 runs East from NewYork to California.. you have interstate 95 runs from Miami to NewYork.. you have interstate 77 it will run from upper Cleveland all the way Dow n to South Carolina into interstate 10 From Florida to Texas… and many many more but these the interstates that take you across country
美国有很多州际公路，比如80号州际公路从纽约向东延伸到加利福尼亚。95号州际公路从迈阿密延伸到纽约。77号州际公路从克利夫兰北部一直延伸到南卡罗来纳州，然后与从佛罗里达到德克萨斯的10号州际公路相连……还有很多其它的州际公路，但这些是横跨国家的州际公路。

There are lots of things you could be wondering about and you may even be asking yourself, what is the longest interstate in us? As we all know that interstate highways are comprised of bridges, roads, tunnels, and freeways. Now let's take a look at how long these segments of the interstate are:
In terms of the longest interstate in us, there are the six segments of I-70, I-495, I-85, I-395, I-95, and I-395. Those are just the longest segments of the interstate highway system. Some people have inquired about the other interstate segments but because of space limitations and the lack of land in some areas, the average length of the major highway segments can't be measured.
All the six segments of the I-70 in the US are also known as the Trans-Mississippi Interchange. The longest interstate in us also takes up the eastern half of I-75 in the country, from New Jersey to Virginia.
你可能会好奇很多事情，甚至可能会自问：美国最长的州际公路是哪一条？众所周知，州际公路包括桥梁、道路、隧道和高速公路。现在，让我们看看这些州际公路的各个部分有多长：
在美国最长的州际公路方面，有六段公路：I-70、I-495、I-85、I-395、I-95和I-395。这些只是州际公路系统中最长的部分。有些人询问了其他州际公路的部分，但由于某些地区的空间限制和土地不足，主要公路段的平均长度无法测量。
美国I-70的所有6段也被称为跨密西西比州际公路。美国最长的州际公路也占据了I-75的东半部，从新泽西到弗吉尼亚。

But before you head to your nearest state to find out the answer to the question, "What is the longest interstate in us", you should know that some of the segments are actually the same. There are three interstates which are combined and are broken down into two parts: I-76, I-81, and I-279. These three sections are the shortest segments of the interstate highway system and are all the same.
We have had several states in the US grow through the last decade and they are growing as well as the highways have grown. This has led to the completion of the largest expansions in our history, which has opened the way for the expansion of the interstate highway system.
These highway expansions are constructed and made operational for the purpose of connecting and providing access to growing urban areas and to other areas where people need to travel. The longest segments of the interstate highway system are found in areas that were previously rural and remained so until recently. The name of this last section is the last of the Interstates in the East, the last segment of the Interstate system.
但在你去最近的州寻找“美国最长的州际公路是什么”这个问题的答案之前，你应该知道有些路段实际上是一样的。有三条州际公路是合并在一起的，并且被分成两部分：I-76、I-81和I-279。这三个路段是州际公路系统中最短的路段，而且都是一样的。
在过去的十年里，美国的几个州都在发展，它们的发展速度和高速公路的发展速度一样快。这导致了历史上最大规模的公路扩张，为州际公路系统的扩张铺平了道路。
这些公路扩张是为了连接和提供通往不断发展的城市区域以及其他人们需要旅行的地方。州际公路系统最长的部分位于以前是农村地区并且直到最近仍然是农村的地区。这段公路的名称是东部州际公路系统中的最后一段，也是整个州际公路系统的最后一个部分。

Today, this area becomes the gateway to the United States of America, and the final stretch of freeway that lix the other Western States together. It serves as a final refuge for those who cannot get into the big cities and communities because of its size and significance in the world economy.
When it comes to adding length to the highways, the options are numerous.
A final part of the interstate system for the East, the final stretch of I-77 was completed in 2020. This is a local freeway in Virginia, which connects Washington DC and the DC Metropolitan area. It is more than forty miles long and has eleven lanes in each direction.
如今，这个区域成为了美国的门户，是连接其他西部各州的最后一段高速公路。对于那些因为其规模和在世界经济中的重要性而无法进入大城市和社区的人来说，它是一个最后的避难所。
当涉及到增加公路长度时，有很多选择。
东部州际公路系统的最后部分，I-77的最后一段在2020年完成。这是弗吉尼亚州的一条地方高速公路，连接华盛顿特区和华盛顿大都会区。它超过40英里长，每个方向有11条车道。

I think Interstate 95 could be reasonably said to be the most important highway. It passes through 15 states along the east coast, connecting Boston, NYC, Philadelphia, Baltimore, Washington DC, and Miami, as well as dozens of secondary cities, like Portland, Providence, New Haven, Bridgeport, Newark, etc, etc.
我认为州际公路95号可以被合理地认为是最重要的高速公路。它沿着东海岸穿越15个州，连接了波士顿、纽约市、费城、巴尔的摩、华盛顿特区和迈阿密，以及波特兰、普罗维登斯、纽黑文、布里奇波特、纽瓦克等数十个二级城市。

Great question! I ‘simply’ cannot decide. Ranked by personal experience: I-95 connects the most people in sheer multitudes, and at first glance I suppose that means most ‘important’. But there's I-40…because of Winter weather, lixing freight and people nearly coast to coast, its overall length, and it being centrally accessible to the whole nation, it's thusly more ‘important’ than I-10 (fourth most in my estimation). However, most ‘importantly’ because of a lack of many viable alternatively accessible, continuously designated routes, and its connectivity to multitudes of people and freight as well, I'd choose I-5 for being extremely ‘important’ and perhaps the most as a consequence. ‘Importance’ calls for subjective interpretation. Enjoyed the comparisons!
很棒的问题！我“实在”无法决定。根据个人经验排名：I-95连接了最多的人，乍一看，我猜这意味着它最重要。但还有I-40……因为冬季天气，它连接了货物和人员，几乎横跨整个国家，它的总长度，以及它对整个国家的中心位置，使它比I-10（我估计第四重要）更重要。然而，最重要的是，由于缺乏许多可行的替代路线，以及它连接了众多的人和货物，我会选择I-5，因为它极其重要，也许因此而成为最重要的。“重要性”需要主观解释，我喜欢这些比较！

What is the longest interstate highway in the United States?
Interstate 90, running from Washington SR 519 in Seattle to Massachusetts Route 1-A near Logan Airport, Boston, is 3,020.44 miles in length.
Between Illinois and Massachusetts, Interstate 90 was placed upon or incorporated from various toll roads. Pennsylvania is the only state east of Chicago that carries no tolls on 90.
美国最长的州际公路是哪条?
州际公路90号，起点位于西雅图的华盛顿州519号公路，终点在波士顿洛根机场附近的马萨诸塞州1-A公路，全长达到3,020.44英里。
在伊利诺伊州和马萨诸塞州之间的路段，州际公路90号有部分是建立在原有收费公路的基础上，或者是将这些收费公路纳入其中。在芝加哥以东的所有州中，宾夕法尼亚州是唯一一个在州际公路90号上不收取任何通行费的州。

Interstates are generally limited access (1.) Some come with tolls; and 2.) don't have stop lights and have an on/off ramp.) and were created as a part of larger defense network of roads across America created under Eisenhower.
Thus: Even-numbered interstates (such as I-10, I-20, I-8, I-90, I-88, etc.) run west-east. You may have three-digit interstates that end in even numbers (such as I-290, I-110, I-278, etc.)
州际公路通常是限制性通行的，这意味着它们：
1、有些配有收费站；
2、不设红绿灯，而是通过上下匝道来进出。
它们是美国在艾森豪威尔总统的领导下创建的更广泛的国防公路网络的一部分。
因此，偶数编号的州际公路（例如I-10、I-20、I-80、I-90、I-88等）是沿着东西方向延伸的。同时，你也可能会看到一些三位数的州际公路编号，这些编号以偶数结尾（例如I-290、I-110、I-278等）。

因此，偶数编号的州际公路（例如I-10、I-20、I-80、I-90、I-88等）是沿着东西方向延伸的。同时，你也可能会看到一些三位数的州际公路编号，这些编号以偶数结尾（例如I-290、I-110、I-278等）。
Odd-numbered interstates, on the other end (such as I-5, I-35, I-75, I-95, I-35, I-99, etc.) run south-north. You may have three-digit interstates that end in odd numbers (such as I-395, I-205, I-787, etc.) All of these interstates are lixed to the larger interstates that face them (regardless of direction).
U.S. Highway designators were approved in 1926 and is a set of state/multi-state roads with a coordinated pan U.S. route designator (such as U.S. 1, U.S. 395, U.S. 40, U.S. 30, U.S. 15, U.S. 20, etc.) In addition, you have forest highways, state highways that have their own insignia, and county roads (or parish roads, in the case of Louisiana).
This is why you will see multiple highway signs on the same route - these routes all share a common highway segment (this is called "concurrency") When they diverge, signs will indicate which direction to take at the appropriate junctions.
另一方面，奇数编号的州际公路（如I-5、I-35、I-75、I-95、I-35、I-99等）是南北走向的。你也可能会看到以奇数结尾的三位数州际公路（如I-395、I-205、I-787等）。所有这些州际公路都与它们面对的较大州际公路相连（不论方向）。
美国公路的命名规则在1926年被批准，它是一组具有统一全美路线编号的州内或跨州公路（如US 1、US 395、US 40、US 30、US 15、US 20等）。此外，还有森林公路、各自有标识的州公路，以及县级公路（在路易斯安那州则是教区公路）。
这就是为什么你在同一条路线上会看到多个高速公路标志——这些路线共享一段共同的公路（这称为“共线”）。当它们分岔时，在适当的路口，指示牌会指示你应该朝哪个方向前进。

Like others have said, the system of US highways predates the Eisenhower Interstate system.
Both have standards for road construction (lane width, road bed, shoulders, etc.) The Interstate Highway system is more strict than the US Highway system (2 lanes each way, divided highway, limited access, and better road beds, etc.) A US Highway may be anything from a 2-lane road with shoulders to a limited access, multiple lane highway - and may change from one form to another over it's length - even within the same city.
US-66 is probably the most famous US highway.
正如其他人提到的，美国的公路系统在艾森豪威尔州际公路系统之前就已经存在了。
这两个系统都有道路建设的标准，比如车道宽度、路基、路肩等。但是，州际公路系统的标准比美国公路系统更为严格，例如要求至少有两个车道、分隔式公路、限制性通行，以及更好的路基等。美国公路则可能从带路肩的双车道公路到多车道的限制性通行公路不等，甚至在同一个城市内，公路的形式也可能发生变化。
美国66号公路可能是最著名的美国公路。

Numbering of the two systems is "opposite" in order to reduce the number of times the same number is used twice in the same location. For instance, US highway numbers increase from north to south, and from east to west. Interstate highway numbers increase from south to north, and from west to east.
As other people have said, route numbers (both Interstate and US highway) may be overlain on the same highway. (For instance, I-75 and US-23 in the northern parts of Michigan, I-275, I-96, and I-696 in SE Lower Michigan, I-80, and I-90 across northern Ohio and Indiana.)
Standards change over time, and as the US Highway system is older, there are more routes that are on highways that would otherwise be considered substandard currently (narrow lanes, poor entrances and exits, etc.) There are even a few instances where there are (or have been) draw bridges (and requisite stop lights) on Interstate Highways.
为了避免同一地点出现重复使用相同编号的情况，两个系统的编号方式是相反的。美国公路的编号从北向南递增，从东向西递增；而州际公路的编号则是从南向北递增，从西向东递增。
正如其他人所说，州际公路和美国公路的路线编号有时会重叠在同一条公路上，例如，在密歇根州北部的I-75和US-23，密歇根州东南部的I-275、I-96和I-696，以及穿越俄亥俄州和印第安纳州北部的I-80和I-90。
随着时间的推移，这些标准也在不断变化。由于美国公路系统较早建立，所以有些路线可能按照当前的标准来看已经不符合要求，比如车道过窄、出入口设计不佳等。甚至在一些州际公路上，还存在着（或曾经存在过）吊桥和必要的红绿灯。

Most of the answers are correct in the timing of the US Highways predating the Interstate Highway system, but there are several other differences.
US Highways do not generally have full access control. In other words, it is not uncommon to have driveways on the US Highway.
There are also intersections on US Highways; usually 4 way intersections that may or may not be modified by now. They generally have signals or some from of stop control Interstate highways, or freeways, have interchanges that do not have signals or stop control.
We still build and maintain US Highways. Even though they may predate the interstate, it doesn’t mean that we don’t build them or maintain them anymore. We don’t usually build a new US Highway and call it that, but we will realign and modify existing US Highways to improve the conditions for drivers.
US Highways often run through the middle of the main street of a town or city. Interstates may run through downtown, but there is very little direct access to it.
Speeds on US Highways are generally below Interstate speeds, but can be as high as the interstate.
That is just a sampling of the difference between US Highways and Interstate Highways.
大多数回答都正确地指出了美国公路系统早于州际公路系统的出现，但它们之间还有一些其他的区别。
美国公路通常不实行完全的通行管制。换句话说，在美国公路上，有私人车道直通是不足为奇的。
美国公路上还设有交叉路口，通常是四路交叉口，这些路口可能已经被改造，也可能还没有。它们通常配备有交通信号灯或某种形式的停车控制。相比之下，州际公路或高速公路拥有立交，这些立交不设交通信号灯或停车控制。
我们仍然在建造和维护美国公路。尽管它们可能早于州际公路系统，但这并不意味着我们就不再建造或维护它们了。我们通常不会新建一条公路并称之为美国公路，但我们会重新规划和调整现有的美国公路，以改善驾驶者的条件。
美国公路常常直接穿越城镇或城市的中心街道。州际公路虽然也可能穿过市中心区域，但通常提供非常有限的直接接入。
美国公路的限速一般低于州际公路，但有时也可能与州际公路的限速一样高。
这仅仅是美国公路与州际公路之间区别的一小部分。
