Longest street in the United States.

Opps, my mistake. It does look like it shares some stretchs with a couple of state routes, but only for short runs due to thier only being a need for one road and Grand River was already there.

Every road in California long enough to be considered here is going to have some route number attached to it.

I know that Broad St. in Columbus OH is 31 miles long (or a bit longer). The actual road is MUCH longer, but it changes names once it gets way outside Columbus.

Another big one through Ohio is the National Road, which is called National Rd through much of the state. It’s Main St. in Columbus, but it’s just one road. Here’s a site that lists it as 824 miles long through several states. Does that count?

I don’t think that’s what the OP is after:

Bolding mine.

Interestingly enough, U.S. 40 also includes Colfax Avenue through Denver.

Like Garygnu (loved that show, btw), most roads that are anywhere near this length are going to be numbered, either state or US.

Wisconson Ave/Rockville Pike/Market Street/Hungerford Drive is +42 miles long (this is distance from the border of D.C. to Frederick MD- but the Road runs through each so it is a bit longer than that. )

Cheat(?):
It does not have the same name through all the jurisdictions.

There is peice of it that is part of the Highway system - because it is an artery of the Beltway. But it is a road and not a Highway.
From Georgetown in D.C. it will eventually widen to 6 lanes and will eventually return to a 2 lane road as it winds from th Potomac to past the Monocacy River…It is an old Tobacco Road and predates the United States

Well I keep waiting for the axe to fall and it hasn’t so I’ll od it:

RTFT before you post next time Jimmmy. The OP says within the same jurisdiction. Your post is so screwed up & violates so much of what was asked that it is inappropriate Champ – it is actually a bit painful. You owe all the people who read this thread and posted in good faith an apology you nitwit

I want to bump the thread so that someone can make a sensible post and apologize.

In my travels through several Midwestern, I always find myself crossing an east-west street named “Lincolnway”. They all seem to be close to I-80. Could that be the longest street?

I believe much of I-80 parallels US-30, which was (and perhaps still is) theLincoln Highway. Though no doubt much of it is “Main Street” or “Harrisburg Pike” or other such intriguing names, the “Lincolnway” portions are units of it retaining a variant on the old name.

I find it very interesting that some jurisdictions retain former highway numbers as road names. For example, NC Highway 1700 runs east-west about a quarter mile north of my home. Its number is route 1700, a secondary road. Its name in Franklin and Nash Counties is “Old US Highway 64” – having been that route prior to construction of the current limited-access freeway that is US-64.
