Title: Longst 6+ lane surface road?
Post by: froggie on May 01, 2019, 11:49:02 AM
Something I've been pondering lately, in part because of watching Pasco County, FL too many times on LivePD.  A quick search does not find any older threads on this.

Wondering what the longest stretch of surface (i.e. non-freeway) roadway is that is at least 6 through lanes.  One candidate would be US 19 from just north of FL 580 (where the freeway section outside Clearwater and St. Pete ends) to FL 50, just over 37 miles.

Any segments that are longer?

NY 104 in Greece, NY has a six lane segment of just over six miles (https://www.google.com/maps/dir/Keeler+St+Expy,+Rochester,+NY+14621/43.2149799,-77.7338533/@43.2059319,-77.7035714,13.21z/data=!4m8!4m7!1m5!1m1!1s0x89d6b428ff57a3df:0xb62ed0cb8def6e64!2m2!1d-77.616706!2d43.1914152!1m0). Of course, that doesn't even come close to touching 37 miles. That'll be tough to beat.

Right out of the gate my top places to look would be Philadelphia, Washington DC, Toronto, and Chicago. I thought US-29 (Columbia Pike) between Silver Spring and Ellicott City, MD, would be a good candidate, but there are some four lane sections, in addition to segments that function as a full freeway.

There are very few of these at all in MSP, the longest probably being the section of France Avenue in Edina and Bloomington between 62 and just south of 494. Certainly not 37 miles. :D

I did look at that but the longest I came up with for MD is MD 355 from DC to Gaithersburg.  But that's still a bit less than 20 miles.

Dakota County 23 (Cedar Ave) is just over three miles, although it feels a lot longer than that. No idea if that beats France Ave or not.

Top of mind Colorado candidates would be SH 83 (Parker Rd) at 13 miles between Chambers Rd and Bayou Gulch Rd and SH 21 (Powers Blvd) through the east side of Colorado Springs at 15 miles.  That 37 mile stretch may be tough to beat!

I immediately thought of North Ave/IL 64 in the Western Suburbs of Chicago...but a quick check with Google Maps puts the 6 lane section at about 16 miles

IL 13 in Williamson County IL into Marion is about 10 miles of 6 lane. If IDOT ever filled in the 6 lane gap between Cambria Rd and Carbondale/near Crab Orchard Lake, it would increase to 18 miles

Still not all that close to 37 miles, tho

8 Mile Rd., on the northern border of Detroit, is a divided surface road that is 3 or more lanes each way from Grand River Ave. to the west to I-94 to the east, a distance of 20.7 miles.

EDIT: Looks like it's around 15 miles or so.

Lot of 6+ lane surface streets in Florida, but I can't seem to find any that top 37 miles. Looking in central Florida, the best contender I could think of off the top of my head is John Young Pkwy, which as of now is 17.7 miles from US 192 to SR 50. I think a widening project is underway to make it 6 lanes up to Edgewater Dr, bringing it up to 21.8 miles.

8 Mile Rd., on the northern border of Detroit, is a divided surface road that is 3 or more lanes each way from Grand River Ave. to the west to I-94 to the east, a distance of 20.7 miles.

Lot of 6+ lane roads in metro Detroit as well. It looks like Telegraph has you beat, since it's 6+ lanes from Elizabeth Lake Rd in Pontiac to the I-75 connector in Taylor, a distance of 31.9 miles.

I genuinely didn't believe it until I mapped the two endpoints. It really is incredible how sprawling and just massive, area-wise, the Detroit metro area is. There is no other city in the US in which you could drive 32 straight miles like that on a surface street and still be in the same urbanized area. That's just slightly less mileage than downtown Baltimore to downtown DC.

Except for about 3,000 feet east of Warbro Road eastbound. 

Still 2 lanes, but the county has a project to rebuild it to 3 lanes.

Route 360 Eastbound (Lonas Parkway to Castle Rock Road) Widening

An additional eastbound lane will be added to Route 360 between Lonas Parkway to Castle Rock Road.

Preliminary engineering is underway and 60% plans have been developed.

Construction anticipated for Summer 2020.

Cedar stretch is slightly longer than the France stretch.  But neither tops Bottineau Blvd/CSAH 81 which is now 6 lanes from 100 to 94/694 and slated to continue up to 169.  But even that is just barely 3 miles.  Everything in the Twin Cities combined doesn't even come close to matching some of the individual roads mentioned elsewhere in this thread.

For California, I immediately thought of 19th Avenue in San Francisco (CA 1) and El Camino Real (CA 82). The 6 lane part of 19th Avenue + Crossover Drive is only 4 miles though.

CA 82 is a surface street arterial from San Francisco to San Jose, but surprisingly to me not all of it is 6 lanes. In Daly City just south of SF, it is only four lanes, but once it gets to Colma (Serramonte Blvd, maybe sooner), it is 6 lanes all the way to its terminus at I-880. If so that makes it a 6-lane surface road for at 40 miles or maybe more!

Maybe someone else can chime in about how much of CA 82 is six lanes or if there's any other notable candidates outside the Bay Area

Hmm...sounds familiar

Another in Phoenix...Grand Ave almost pulls off 24 miles...except for a very quick lane drop and add for Exit and Entrance ramps @ 27th Ave/Thomas Rd

(Bronx County), New York City.  They all have significant stretches of six lanes or more in any direction.

US 74/Roosevelt Boulevard here in Union County has a three lane segment roughly four miles long, similar to other three-laned lengths in this thread (such as 6 miles). Not that long but sure feels like it with the traffic volume on it.

Edit: it's no longer 53.5 - there's a section with just four lanes from FL 806 to FL 804, resuming to 6 lanes again to FL 704.

Florida State Road 7 (mostly US 441) 6-lane section, at 37 miles (https://www.google.com/maps/dir/25.9371478,-80.2049018/26.7093237,-80.200924/@26.3236114,-80.5005352,10z/data=!4m5!4m4!2m2!1b1!2b1!3e0); from the intersection with SR 806 in Delray Beach continuously south to NW 177th Street in North Miami. There's almost no curves and nothing to dodge along the route. The lanes drop to four over I-95 at the Golden Glades Interchange complex.

That also brings up one of the longest continuous 8-lane sections I know of; SR 704 from South Dixie Highway (US 1) to a point a half-mile west of SR 7 is 9ス miles in length (https://www.google.com/maps/dir/26.7064154,-80.0552316/26.7095229,-80.2091473/@26.7090923,-80.2105249,16.61z/data=!4m5!4m4!2m2!1b1!2b1!3e0).

Heck, everything in Upstate NY combined probably doesn't top 37 miles.

(One time back in the '80's me and my dad drove the whole way from Serramonte Blvd. in Colma to San Jose on Ca. 82 and even back then it took forever but it was interesting.)

There's almost no curves and nothing to dodge along the route. The lanes drop to four over I-95 at the Golden Glades Interchange complex. As the development is less dense north of US 98, and there's a lot more preserves, I don't think SR 7 will be widened in the immediate future.

That also brings up one of the longest continuous 8-lane sections I know of; SR 704 from South Dixie Highway (US 1) to a point a half-mile west of SR 7 is 9ス miles in length (https://www.google.com/maps/dir/26.7064154,-80.0552316/26.7095229,-80.2091473/@26.7090923,-80.2105249,16.61z/data=!4m5!4m4!2m2!1b1!2b1!3e0).
I can recall when SR 7 dropped to two lanes at the Broward/Palm Beach county line.

The 4-lane segment that is sandwiched by 6-lane segments is the rather rustic portion through Burlingame, mostly residential area with some pavement surface issues due to tree roots.  Probably the one portion of Route 82 that is most reminiscent of when that part of the road was US 101.

I believe the longest such segment in Virginia is US 360 west out of Richmond, at around 14 miles give or take...

I was thinking US 250 between I-95 and just west of VA 288, but there's a very brief lane drop EB at Glenside Dr/I-64 and again both directions at I-64 Short Pump.

Also noteworthy is VA 143 in Newport News from just west (north) of I-664 to Glen Cove Ln.

US 58 in Norfolk & Virginia Beach between Ballentine Blvd and the US 58 BUS split could've been a contender but it has a 4-lane section with frontage roads in the area of I-64.

8 Mile Rd., on the northern border of Detroit, is a divided surface road that is 3 or more lanes each way from Grand River Ave. to the west to I-94 to the east, a distance of 20.7 miles.
Lot of 6+ lane roads in metro Detroit as well. It looks like Telegraph has you beat, since it's 6+ lanes from Elizabeth Lake Rd in Pontiac to the I-75 connector in Taylor, a distance of 31.9 miles.

I genuinely didn't believe it until I mapped the two endpoints. It really is incredible how sprawling and just massive, area-wise, the Detroit metro area is. There is no other city in the US in which you could drive 32 straight miles like that on a surface street and still be in the same urbanized area. That's just slightly less mileage than downtown Baltimore to downtown DC.
I never thought of the Detroit metro area being that big area wise it's mainly just three counties (Wayne, Oakland and Macomb) but as far as Telegraph goes it runs through the longest length of the metro area. Another long street in the Detroit area is 12 Mile Road which runs straight for 32 miles from Beck Road in Wixom to Jefferson Avenue in St. Clair Shores, west of Beck Road it's discontinuous until it ends for good at Milford Road about 5 miles west of Beck. I don't think that 12 Mile is ever six lanes though, just a really long street.

Detroit is the 9th largest urban area by area though in the U.S. which is kind of surprising. In some areas on Telegraph though those lanes are really needed especially in the area between 12 Mile and the Mixing Bowl which has a VPD count of around 90,000. The reason that Telegraph Road runs the coarse it does btw is because it was built along side the Telegraph lines that ran from Dearborn to the south which is why it's named Telegraph Road.

I see that now but it's still probably the best example in the Detroit area, can't think of another one in Michigan and Telegraph's stretch isn't 37 miles so Michigan doesn't have that beat. I can't even think of one in my city that has six lanes for any stretch, a weird example is M-58 starts out at on a set of one way streets at I-675 and has three lanes for the westbound street and two for the eastbound street, they merge together about a quarter of a mile west of Saginaw city limits to run on a two way street but they keep the same number of lanes they had as the one way street with a turn lane, so you have three lanes westbound, a turn lane and two lanes eastbound on the two way stretch.

I知 surprised no one has mentioned Dallas.

Why?  Is there a really long six-lane surface road there?  If so, what is it and how long?

My first thought on this was "China will probably have it." But it's really hard to look when Google Maps doesn't line up with Google Maps Satellite for that country only. And everything I found so far was four lanes or limited access.

I was actually thinking something in the Middle East like Saudi Arabia or the UAE. Some of those long freeways might be more like some Western state interstates where there is some access to the highways. However, the few I checked the access was still right on/off.

This depends on whether we allow roads with a few scattered interchanges but by-and-large are at-grade, and whether we allow it to be 4 lanes through an interchange with the rest on frontage roads. If those situations are OK, TX 6/FM 1960 appears to qualify (https://goo.gl/maps/zZHPQiVQQvikWjGp8) from Gordon Street in Alvin all the way around to FM 1960 Business in Humble, a distance of 74.7 miles.

I値l have to look more into it but it seems Dallas has some pretty long 6 lane surface roads. I would think it would be a strong contender for the longest six lane surface road in an urban area.

The OP has one at 37 miles, and you can drive clear across the city of Dallas in less than that.  Heck, downtown Dallas to downtown Fort Worth is less than 37 miles.

Preston Rd (TX 289) comes close. From Loop 12/Northwest Hwy to Frontier Pkwy is about 30 miles. That was the first street that came to mind from the little time I spent in Dallas.

If everyone is OK with pretending it doesn't narrow to 4 lanes at the SRT (https://goo.gl/maps/FfXEGWNLkXcnTHSt6)...

I had considered that, but the fact that it splits into the two through lanes in each direction and two lanes to access the tollway's frontage roads (which also are through lanes--a total of 4 actual through lanes in each direction), I counted those as part of the 6+ lane configuration.

The longest in Washington: SR 99 between Mercer Street and I-5 in Everett (https://www.google.com/maps/dir/47.6247385,-122.343602/47.9134151,-122.2121142/@47.7689905,-122.4198172,47212m/am=t/data=!3m2!1e3!4b1!4m4!4m3!2m1!1b1!3e0), clocking in at 22 miles. It could be extended all the way down to Federal Way if the downtown tunnel wasn't 4 lanes wide.

I found one in Dallas, kinda: https://www.google.com/maps/dir/32.7343225,-96.710959/Unnamed+Road,+Richardson,+TX+75081/@32.8782302,-96.6856963,12z/data=!4m16!4m15!1m5!3m4!1m2!1d-96.5989576!2d32.7437152!3s0x864ea53f5a296a53:0xe225b2787ac51622!1m5!1m1!1s0x864c1eff98bfb919:0x6c4b843e83bd422c!2m2!1d-96.7043288!2d32.9455548!2m1!1b1!3e0

25.3 miles. Starts as Lake June Rd in Pleasant Grove (neighborhood of Dallas), becomes Belt Line Rd in Balch Springs and passes through Sunnyvale, Mesquite and Garland before going down to 4 lanes in Richardson.

Just remembered that US 441 / SR 7 has a break with just four lanes from FL 806 to 804. That makes it 37 miles from FL 826, and not the 51 miles I'd mentioned up-thread.

8 Mile Rd., on the northern border of Detroit, is a divided surface road that is 3 or more lanes each way from Grand River Ave. to the west to I-94 to the east, a distance of 20.7 miles.
We're getting there
Woodward Ave from Detroit to Pontiac is roughly 25 miles.  I think all of it is at least 6 lanes - some areas 8 or even 10.

Edit: Then I read the posts about Telegraph Rd.

Don't judge me, I've never been on a long six lane surface road and this was the best i could find.
