Title: Busiest 4-lane highways
Post by: tolbs17 on February 24, 2022, 11:50:26 AM
US-64/264 (future I-87) between Wendell and Zebulon. Around 60,000 AADT

I-40 between the I-85 split and US-501. Around 70,000 AADT (Widening to 6 lanes is already underway)

I-40 near Hickory, NC around 70,000 AADT.

I-485 in southeastern Charlotte. around 75,000 AADT.

If I-95 around Florence SC was never widened then it would qualify on this list.

VA-168 in Chesapeake. Has around 60,000 AADT.

Same with I-64 in the southern part. Has around 80,000 AADT.

I-664 too. 75,000 AADT.

Isn't this topic pretty much the same as the 4 lane freeways that needs to be 6 laned thread, as both involves the busiest 4 lane freeways?

Regardless, some off my mind:

-  I-81 at some point probably qualifies, solely from the truck traffic

- I-40 Little Rock to Nashville

- I-70 Kansas City to St Louis

- All 4 lane parts of I-65 in Indiana

- Remaining 4 lane section of I-75 in Ohio

- Remaining 4 lane section of I-65 north of Nashville in TN.

tolbs, I have a suggestion for you.  If you would like to start a Carolina-centric topic daily, there is a Southeast regional board that would likely get you more traffic.

Yeah but I'm talking about just busy 4 lane highways in general. they may or may not get widened.

Not really. A highway could just be steadily busy without being overwhelmed during peak periods.

I-440 in West Raleigh takes the cake with 85,000 AADT. Improvements should have been done in the 90s, but I have a feeling it was delayed numerous times. Although there is active construction going on there.

From a quick glance from this thread (https://www.aaroads.com/forum/index.php?topic=28578.0), Maine's I-295 has an AADT of 83,830 at one point when it's only 4 lanes.

You and your cake taking... which of course is always about something in NC. Should probably have mentioned it in your original post if it's that noteworthy.

Also I bet I-5 in Portland is higher. Oregon doesn't make their traffic data easy to find, so someone more familiar with those websites can dig up the numbers if they want.

Where is I-5 only 4 lanes through Portland?  I can look up the AADT if you direct me to a spot.  Every place I've spot checked on GSV is 3+.

Edit, found it between I-84 and I-405.  From the other thread it looks like 120,000.  The I-76 on the Schuylkill Expressway is 140,000 which as of the last thread, is the winner.

I-80 in Joliet IL 79,700 just east of Richards St. (soon to be 6-laned)
I-57 in Matteson IL 74,000 just north of Vollmer Road
IL 394 in Lansing/Thornton IL 71,100 just south of the 80/94/294 junction

I think there were sections of I-55 between I-80 and IL 53 that were higher than 80k prior to the 6-laning in the late 2000s, but IDOT's online AADT history doesn't go back that far.

Hutchinson River Parkway between Exit 5 and Exit 6A has an AADT of 117547, as of 2019 according to NYSDOT. Also, a section of I-278/BQE in Brooklyn Heights has been restriped from 6 to 4 lanes. Before the restriping, the AADT was 144932.

Probably some higher in PA as well, which is (in)famous for four-lane freeways in urban areas. I'll work on finding some volumes, but my guess is parts of PA 28, I-76, I-376, and I-476 have at least 85k or more.

Some of the heavy hitters from Maryland (Note: I used MDOT SHA's 2019 traffic volumes (https://roads.maryland.gov/Traffic_Volume_Maps/19_Traffic_Volume_Maps.pdf#page=1&zoom=100) prior to COVID-related traffic reductions):

-MD 295/B-W Parkway south of MD 197 at 117,322
-US 15 thru Frederick at 112,101
-MD 100 east of I-95 & US 1 at 99,610
-I-97's southernmost stretch at 98,731
-I-270 north of the drop from 6 to 4 lanes at 89,211
-I-70 west of US 29 at 88,391
-US 50 east of MD 201 & MD 295/B-W Parkway at 88,000
-I-70 over South Mountain at 82,292

I-895 thru the Harbor Tunnel probably ranks somewhere in the middle of that list, but it seems traffic data within Baltimore City might be located elsewhere (as MDOT SHA, despite being headquartered in Baltimore, does not have any jurisdiction there).

A few from Washington:

I-5 between Burlington and Mount Vernon - 81,000 AADT (2019)
SR 520 over Portage Bay in Seattle - 86,000 AADT (2019)
SR 520 Floating Bridge - 74,000 AADT (2019)

ODOT is actually pretty good relative to the Northwestern DOTs, with a dedicated page (https://www.oregon.gov/ODOT/Data/Pages/Traffic-Counting.aspx) for all of their traffic count documents. Just requires knowledge of their internal numbering system.

From the 2018 TVT (https://www.oregon.gov/odot/Data/Documents/TVT_complete_2018.pdf), it looks the four-lane section of I-5 through Albina had an AADT of 118,400 crossing over NE Holladay Street (a bit north of the I-84 interchange).

Not really. A highway could just be steadily busy without being overwhelmed during peak periods.

TWO lanes can handle 86400 vehicles per day at a 2-second following distance, if they are steady and consistently spaced. Queuing theory, however, says that that is not what you will probably get. Throughput drops quite abruptly when you get over about 40% theoretical capacity. There are plenty of roads that might as well not even exist 23 hours per day. They get basically all of their traffic in 30 minutes in each direction. I'm thinking of roads that lead to a heavy commute or sports or entertainment event destination.

I found 130,000-140,000 for the Schuylkill Expressway around Manayunk and the Conshohocken Curve.

For the Blue Route, 48,000-78,000 in Delaware County. Seems low!

For the Parkway East, around 88,000-98,000. Parkway West tops out just over 100,000.

For PA 28, topping out around 78,000.

US 22 in Lehigh County runs around 88,000 between PA 309 and PA 378, and gets over 100,000 crossing the Lehigh River.

I-81 between Paxtonia/Linglestown and I-78 is generally around 63,000 (more suburban/rural, but still very busy for a 4-lane Interstate).

US-23 between Flint and Brighton carries between 40,000-50,000 VPD and is only four lanes.
Between Brighton and Ann Arbor it goes up to almost 60,000 VPD with the flex lanes between Whitmore Lake and M-14's western split.
On the part where M-14 runs concurrent with US-23 there is over 75,000 VPD with six lanes.
On the east side of Ann Arbor between M-14 and I-94 it has over 60,000 VPD and again is four lanes.
Between Ann Arbor and Toledo it drops down to about 28,000 VPD south of Dundee and has between 30,000-46,000 VPD between I-94 and Dundee which is only four lanes.

So there are portions of US-23 in Michigan that have four lanes and traffic volumes of around 60,000 VPD. It's mind boggling why MDOT hasn't done anything to upgrade this highway other than put in flex lanes for 9 miles but oh they are going to be expanding it to I-96 as if that is actually going to solve any traffic problems. I-75 has lower traffic volumes between Saginaw and Flint and has eight lanes so this really makes no sense.

Some more:

US 422 comes in between 67,000-79,000 between King of Prussia and Royersford, with a surge to 113,000 across the Schuylkill River (the bridge does have an auxiliary lane each way between PA 23 and PA 363).

US 422 also hits 84,000 on the West Shore Bypass between Penn Street/Avenue and US 222/PA 12.

For I-83, 110,000 on its 4-lane section between I-283/US 322 and Harrisburg proper. The recently widened section between Union Deposit Rd. and I-81 comes in at 95,000 (it's now 6 lanes, but traffic was most likely that heavy when it was still 4 lanes).

I-676 is briefly 4 through lanes east of Broad Street (PA 611), at 151,000! (There is an auxiliary lane westbound connecting the ramp from Vine Street and the Ben Franklin Bridge to Broad Street, but underneath Broad Street there are only 4 lanes of traffic total.)

Wisconsin traffic counts can be pulled from this map (https://wisdot.maps.arcgis.com/apps/webappviewer/index.html?id=2e12a4f051de4ea9bc865ec6393731f8). It does contain a variety of traffic count types which means the data doesn't always mesh well. More data can be found at the links found here (https://wisconsindot.gov/Pages/projects/data-plan/traf-counts/default.aspx). Hope this helps.

The reports of 140k ADT on a 4 lane highway are stretching the limits of capacity. Under ideal conditions, a single lane can support about 2,000 vehicles per hour, traveling at around 30 mph by experienced drivers traveling in a fairly well organized platoon. As soon as something out of the ordinary happens, a jam condition occurs upstream and the whole thing breaks down, and you are on the other side of the "capacity curve". Theoretically, the maximum 24 hour capacity of a 4 lane is in the neighborhood of 192,000 a day, which would be the perfect platoon 24/7, and obviously not happening anywhere in the real world. A 4-lane roadway with 140k has to be near or in jam conditions for probably 12+ hours a day.

That sure sounds like the Schuylkill to me. Luckily I have never had the misfortune of driving on the road, but I have often been a witness to heavy congestion on the six lane section between University and Girard from the nearby rail line at varying times and days of the week.

Ted Williams Tunnel in Boston.
I went through it shortly after it opened, before it was connected to the Pike.  It was a breeze...especially compared to the mess that were the Callahan and Sumner Tunnels.

What's the busiest non-freeway four-lane?

OK-9 in Norman (an expressway with stoplights at each intersection) is at 34,300 with no plans to upgrade.

^^ Or a 4-lane city street:  29,500 (2018) on Claude Allouez Bridge in De Pere, WI. East approach is a 2-lane roundabout.  It replaced a 2-lane bridge in 2007.

The short stretch of NY 31 between I-590 and NY 65 is at 42k (data from 2019). Fortunately it's only a short stretch, but south/eastbound still backs up constantly. And it's still pretty busy beyond there, with 33,110 between NY 65 and French Rd.

The section with 42k AADT actually used to have a third lane south/eastbound, but the lane was removed because it became a right-turn only lane and traffic in that lane would be moving at speed while the other two lanes were backed up for the light at NY 65, creating a dangerous situation for anyone trying to enter/exit from any of the businesses along that segment (cars would think it was clear or that drivers were waving them through, only to realize too late that the third lane was still moving). 

That's definitely the highest in this area, as NY 104 in Greece was 6-laned about 10-15 years ago (AADT's roughly 30k-40k on the 6-laned segment). The closest now would be NY 441 where it transitions from expressway to surface street entering Penfield. That's at 32k, and thanks to the overburdened intersection at Five Mile Line, it often backs up a mile plus during the afternoon rush

The BQE triple-cantilever section was at 144k before the lane reduction (and before COVID). Still, it's gotta be near the top if not at the top.

I don't know how busy the new four-lane Midtown Tunnel AADT is. But the old two-lane tunnel was the busiest two-lane road in Virginia at 46,000 AADT (http://www.roadstothefuture.com/Mid_Tunn_Port_Norf_MLK.html). I commuted through it twice daily and it was normal to wait 20-30 minutes on Hampton during the evening rush hour to enter the tunnel. It seriously needed that new second tube.

Really? Former first place is 37K, former second place is 34K, and former third place is 30K. This is across the entire country.

The Midtown Tunnel's second tube opened in 2016, before that thread started.

That's just what people reported on that specific thread that were paying attention to that thread. Nothing official about that list.

Bumping this to ask: I wonder what happens to traffic when you take one of the busiest four-lane surface streets and add a new Whole Foods Markets (the first ever in the Rochester area)?

I don't know yet, but we're about to find out: https://www.rochesterfirst.com/news/business/brighton-whole-foods-planned-to-open-by-february-2023/

What is currently the section of I-41 between Appleton and De Pere, WI with the highest AADT?  It is programed by WisDOT for upgrading from 4 lanes to 6 lanes in the mid to late 2020s.

Mike
Wisconsin traffic counts can be pulled from this map (https://wisdot.maps.arcgis.com/apps/webappviewer/index.html?id=2e12a4f051de4ea9bc865ec6393731f8). It does contain a variety of traffic count types which means the data doesn't always mesh well. More data can be found at the links found here (https://wisconsindot.gov/Pages/projects/data-plan/traf-counts/default.aspx). Hope this helps.

76,200 - Short Duration - I-41 BTWN STH 47 & CTH E - HPMS
54,100 - Continuous - I-41 EAST OF CTH E - APPLETON
51,200 - Continuous - I-41 BTWN STH 441 & CTH N LITTLE CHUTE
58,400 - Short Duration Class - I-41 BTWN CTH N & STH 55 - HPMS
54,200 - Short Duration - I-41 BTWN STH 55 & CTH J
53,400 - Short Duration - I-41 BTWN CTH J AND CTH U HPMS
44,500 - Continuous - I-41 BTWN CTH U AND CTH S DE PERE
46,700 - Continuous - I-41 BTWN CTH F & CTH S INTERCHANGES HPMS
59,100 - Continuous - I-41 BTWN CTH F & CTH G DE PERE #2 (it looks like a lot of traffic is added north of Scheuring Rd.)

I'd hate to see the hourly numbers on this road after a Packer game.

:wow:
