Widest section of freeway in your area

[Buffaboy]

I did a search on this but didn't come up with anything similar to this.

Where I am in the Buffalo area, the widest point would be I-90 at NY 400, where the eastbound I-90 bridge has 5 lanes and the westbound I-90 bridge has 4 lanes including 1 exit lane.

This is tied with I-90 at Cleveland Dr. where traffic between NY 33 and I-290 weaves with I-90 in a section between the Cleveland Drive offramp merge and the Cleveland Drive onramp.

Interstate 5 caps out at 13 lanes just north of downtown Seattle: 5 southbound lanes (including the exit lane for Mercer Street), 4 reversible express lanes, and 4 northbound lanes.

[Beltway]

Richmond, VA -- VA-76 Powhite Parkway, including the James River bridge, 2 miles between Downtown Expressway and Forest Hill Avenue.  Five lanes each way.

There are a couple spots between the Reno airport and I-80 where northbound I-580/US 395 bloats up to 7 lanes.  Southbound has 4 through lanes in that area and sometimes an exit-only lane.  I'm not sure it ever gets up to 12 lanes; it might max out at either 7 + 4 or 6 + 5.

The northbound Lodge Freeway (M-10) opens up to six lanes for a one-mile stretch in Southfield.

10 lanes wide on I-80 in Fairfield, CA because of Traffic from San Francisco and Sacramento.

12 lanes I-80 in Roseville, CA.

[US 89]

The widest freeway in Utah is I-15/80 in Salt Lake City, just north of the Spaghetti Bowl. At the 1700 South bridge, in each direction there are 4 general lanes, 1 HOV lane, and 4 C/D lanes for a total of 18 lanes.

The segment just north of there (between 600 South and 1300 South) has 7 lanes in each direction (6 general, 1 HOV) for a total of 14.

I-15 is 13 lanes just south of the south 15/215 interchange, and 12 lanes between I-215 and 2600 South in Bountiful. It also maintains 12 lanes through the Point of the Mountain.

Portland is I-5 just south of OR 217 at 10 lanes (5 each way). I do not count exit ramps.

LG-TP260

For me, it would be I-84 in East Hartford CT between CT 15 and I-384.  10 lanes (5 each way), plus an HOV lane in each direction.

[jeffandnicole]

Near me, I-76 gets to be 11 lanes wide twice: 6 Lanes West and 5 East, and then 6 Lanes East and 5 West. It's never 6x6 though.

If I count where I-295 and I-76/NJ 42 lay next to each other, it's 13 lanes wide there currently (295N: 3 Lanes; 76W/42N, 4 lanes, 76E/42S, 4 lanes, 295S, 2 lanes).

[ibagli]

In the Columbus area I think it would have to be I-270 through the OH-161/Morse/Easton exits. I think it's 15 lanes (including exit lanes) at one spot.

[slorydn1]

In my immediate area, US-17/US-70 over the twin spans is 3 lanes in each direction until the freeway portion ends at Exit 417.

In my half of the state, I-40 has areas of 4 lanes in each direction up in Raleigh (in a few places there is a 5th lane for short distances between certain exits).

Widest section of freeway in your area

Thruway exit 24 toll booth.

Interstate 80 in Illinois from Brisbin Rd. to Minooka.  Two lane, but with extra wide shoulders, especially over Aux Sable creek. I think the area was widened because they were planning for a third lane through the area.

For me, it would be I-84 in East Hartford CT between CT 15 and I-384.  10 lanes (5 each way), plus an HOV lane in each direction.

I live in Mystic and work in East Providence. This would be the widest freeway section in my area if this is considered my area.  If not, it's probably the Gold Star Bridge or the stretch of I 95 between RI 4 and I 295.

[PHLBOS]

In my area (Philadelphia), it's probably I-95 between I-676 and Columbus Blvd./Exit 20 (aka the Bathtub section): eight mainline lanes with two long parallel ramps (one along each side).

I-75 reaches 16 lanes in two places:

• Very briefly just south of the I-85 merge north of 14th Street: 7 lanes northbound (including 1 HOV) and 9 southbound (including 2 HOV). That's not including the four former southbound lanes no longer in use that now form the median.
  
• Just north of Windy Hill Rd (exit 260) in Cobb County: 9 lanes northbound and 7 southbound. That's not including the currently under construction express lanes (not yet shown in this satellite imagery).

In Grand Rapids area, US 131 expands to 11 lanes at the M-6 interchange. 5 northbound lanes, 4 southbound, and an enter/exit lane on each side.

[wxfree]

In Dallas, I-35E has 13 lanes, all GP lanes, including an exit-only lane to the Dallas North Tollway.  It has 14 if you count an entrance lane that immediately merges into that exit-only lane.

I-635 has 17 lanes east and west of the Dallas North Tollway, including managed and exit-only lanes.

In my interpretation of the topic, I count exit lanes because they're part of the width of the freeway in that section.  The topic is the widest section, not the section with the most through lanes, some of which will disappear later, leading to the question of what qualifies as a through lane.  I wouldn't count an immediate merge or an exit that diverges from a through lane, because that would be width at a single point, not along a section.

Widest freeway in the Boston area - I-95 (MA 128) at US3/Middlesex Turnpike (Exits 32A-B) in Burlington.  11 lanes total - 4 northbound, 4 southbound, one on northbound C/D road, two on southbound C/D road.

For the Capital District, it would be a tie between all the 4:4 sections of freeways.  Nearest one to me is I-87 between NY 155 and NY 2/NY 7 (exits 5-6).  For Rochester, it would be the 5:4 section of I-490 between I-590/NY 590 and Penfield Road (exits 21-22).  And back when I still lived in Rome, it was the 3:3 section of NY 49 between NY 233 and the end of the NY 365 overlap!

Man, I hate to post a Buffalo example that outdoes those two, but I-290 has ten lanes between US 62 (Exit 3) and I-990 (Exit 4). I remembered being impressed with how wide it was, as a kid. But I don't know, maybe that doesn't qualify as "in your area". 


In the Rochester area... yep, vdeane just beat me to it:

it would be the 5:4 section of I-490 between I-590/NY 590 and Penfield Road (exits 21-22).

I-390 at Lyell Ave will also have nine lanes after current construction is complete.
And I'm not sure if this section of I-490 counts as having nine. It looks like it does for several hundred feet - five westbound and four eastbound.

In my area (Philadelphia), it's probably I-95 between I-676 and Columbus Blvd./Exit 20 (aka the Bathtub section): eight mainline lanes with two long parallel ramps (one along each side).

There is a short section of I-95 by the PHL Airport with a 4:3:3:4 configuration (4 in the C-D lanes, 3 in the regular lanes)

If you want to include ramps and C-D roadways --

The I-95 (later I-395) Mixing Bowl Interchange Complex near the Pentagon was rebuilt from 1970 to 1973, as part of the reconstruction of VA-350 Shirley Highway.  The original Shirley Highway was a four-lane freeway.  The Mixing Bowl interchange is where the VA-27 freeway (Washington Blvd.) merges with Shirley Highway and then branches off again.  The original interchange had a merge section each way, about 1/3 mile long, with a third "mixing lane" where the vehicles would weave when they wanted to change to the other freeway.  The rebuilt interchange has the same conceptual movements, but the weaves take place on grade-separated semi-directional ramps.  One cross-section point has 27 lanes on three levels and 10 separate roadways.  Eliminating non-freeway parts of the cross-section, the facility is 18 lanes wide.
