I've always loved driving/riding through cities and comparing the width of the freeways/highways to those of my home base.
In Greensboro... Interstate 85 is 10 lanes wide between Exit 118 and 120. Interstate 40 maintains 10 lanes between exits 208 and 212, and has a short stretch of 12 lanes before/after the 40/73 split.
unfortunately my town's freeway is only 4 lanes. :-|
The widest in the state is 8 lanes, Milwaukee downtown (not including exit auxiliary lanes).
Not counting the toll plazas areas on the Turnpike System, the widest expressway in Pittsburgh is the Parkway North between the North Side and US 19 which is 8 (3 SB/2 HOV/3 NB).
Counting exit ramps and HOV lanes, I believe I-264 in Virginia Beach reaches 16 lanes for a brief stretch, other than that the widest I know of around here is here in Hampton, on I-64 for 2 miles north of Mercury Blvd. (Exit 263) it is 10 lanes not counting exit ramps.
I-95 is the closest highway to my home, and it is 8 lanes in some spots through Philadelphia.
In Oregon...six lanes on I-5.
In my town, I-287 has 6 total lanes.
Most of the freeways in Metro Nashville have 6-8 lanes total. A few spots widen out to 10-12. (including exit ramps)
On the north side of town, they recently completed rebuilding the I-65 / Briley Parkway Interchange (TN 155). The interchange also has extended flyovers to/from Ellington Pkwy. about a mile to the east. On the north side of the interchange, there is 16 lanes total including the entrance and exit ramps.
Even though that is at an interchange, it's still pretty impressive to me for a medium size city like Nashville!
In my town, there is no freeway. Although the widest highway is 4 lanes with some sections that are 6 lanes.
My hometown is Statesville, that HUGE METROPOLIS that it is (NOT).
Both interstates (40 and 77) are four lane through the city.
I-75/85 (Downtown Connector) - 14 lanes or so, in spots.
Be well,

OK 51 between the Muskogee Turnpike and I-44 has 8 through lanes, with 10 lanes inbetween exits.
In metro Sacramento, the widest freeway is probably I-80 northeast of the split with Business 80, which is 14 lanes wide up to Exit 96 (Madison Avenue).
Within the city limits, I suspect the WX Freeway segment of the Capital City Freeway (Business 80/US 50/Route 99) fits the bill at 12 lanes between I-5 and 15th Street (former US 99 and later Route 160).
Sadly US 101 is only 4 total lanes in Rohnert Park at the moment. Definitely needs to be widened.

hopefully one day (within my lifetime) they will widen 77 to at least 6 lanes from the Iredell/Meck line up to Yadkin county line. Preferably 8 lanes from Charlotte to exit 36
The widest highway in New York City Proper is the Trans-Manhattan Expressway, which has twelve lanes at first, although, as you go east, it rapidly sheds lanes. First down to eight after the Harlem River Drive, and then down to six after I-87. This all happens in less than a mile. And you wonder why there's traffic on the Cross Bronx.
I live in NJ and have two close freeways:
I-80 is 6 lanes near my exit (25)
I-84 in NY is very close and has 6 lanes (I think?)

My closest Interstate is I-280 with 6 lanes in my town itself. In my county, I get I-280 up to ten lanes, Garden State Parkway at eight, and the NJ Turnpike/I-95 with a whopping 14!
Also passing through my town in NJ, is I-80, with 6 total lanes. I'm not 100% percent sure of my town border, but I-287 may actually widen to 8 lanes in the northern section of my town (truck lanes for climbing?)
I-10 is 8-9 lanes at its widest point in the city. It will soon be 11-12 lanes in the suburbs
The widest freeway in Hamburg would be the A7 through the Elbtunnel at a total of 8 lanes (2 per tube). Of course, that is unless one of the tubes is once again closed for repairs or because a driver panicked and caused a crash.
Next closest would be around 3 miles of the A1, at a total of 7 lanes, 3 going south, 4 going north. Other than those two, nothing wider than 6 lanes.

Are you including the C/D Roads on I-264 between US 13 and Newtown Rd(?VA 403) when referring to the 16 lanes?
Yeah, but isn't it still that wide for a little bit after the C/D roads end? Meh guess not... but still. C/D roads count.
I-77 from the US 30/62 interchange up through Canton and perhaps all the way to Akron now is six-laned. All two expressways in Massillon, where I live, are four-laned.
I live in Grand Rapids, MI. I-96, I-196 and M6 are all 4 lanes except for a brief portion of I-96 which is 5 lanes. US 131 is 6 lanes through nearly the entire metro area but none of these freeways (with the possible exception of M6) have anywhere near enough lanes. They're planning on adding lanes to I-96 and I-196 near the split but it's going to be a mess to get it done. These freeways were very poorly planned in the first place.
clarification to # of lanes in Milwaukee - I-43 has 4, 5 including the aux lanes
In Madison, WI, just south of the interchange of I-39/90/94, US-151 and High Crossing Blvd, the interstate has three lanes each way, plus two auxiliary lanes (is that the right term?) northbound for the three exits and two lanes southbound -- one from High Crossing Blvd and one from US-151 - for a total of 10 lanes.
If that doesn't count, then the most general-purpose lanes we have is three each way.
collector/distributer is the correct term.
Ah, that makes perfect sense. Thanks!
In Columbus on the I-270 Outerbelt, there is a stretch that is 12 lanes wide counting the C/D lanes to/from the OH161 freeway. I-270 on the north side is 10 lanes wide for a time. This is total of course, not each way. :)
In my town (San Angelo, Tx) the widest highway (U.S 87) is 8 lanes
A portion of US 95 in Las Vegas is currently the widest freeway in Nevada. From I-15 north (west) to Summerlin Pkwy/Rainbow Blvd is 4 lanes + 1 HOV lane + 1 auxiliary lane, or a total of 12 lanes. Runner-up would be I-15 south of US 95, with 4 lanes and an auxiliary in each direction. Other freeway segments in Las Vegas are being planned (or are under construction) to be at least 10 lanes in the future.
Up north, Reno's US 395 widens out to 4 lanes SB/3 lanes NB + an auxiliary in each direction just south of I-80, for 9 total lanes (although the 4-lane part is really 3 lanes with a fourth shoehorned in at the expense of shoulders). A portion of I-80 east of US 395 has a short section with the same setup.
the state route has a center turn lane in part of it in my town...
In Indianapolis, the widest interstate is Interstate 70 west of Interstate 465 on the westside outside the new Indianapolis International Airport terminal. There the highway is 14 lanes wide (including c/d lanes, 6 thru lanes, 8 c/d lanes). This is very impressive for Indiana standards and the highway. Interstate 70 just east of downtown is about 10 lanes wide, all thru lanes, and Interstate 465 on the eastside is at one point 12 lanes wide. The only other places in Indiana the highway is this wide is in Northwest Indiana and outside Louisville.
6 lanes all-general purpose plus 3 for express = I-5 in Seattle
The widest road in Hartford gets up to 12 lanes and it is the split between I-84 and CT-15.
I-15 in San Diego at MP 12 to MP 13 (CA-163 to Miramar Way), is at about 16 lanes across...plus the two express lanes for a total of 18 lanes. They add more lanes every year, so it always changes. I know the I-5/I-805 merge also has a lot of lanes as well...I can't remember because I rarely ever get out that way.
Hard to believe that in 2003, the fire was able to jump the I-15 freeway and go from one side to the other...at the time it had about 16 lanes...
^^ It's also the busiest San Diego freeway now. 302,000 AADT.
Wow! I think that's even higher than any highway here.
^^ That's correct, the busiest freeway in the San Francisco Bay Area is the I-80 near Emeryville (just north of I-880) at 294,000 AADT. The San Francisco-Oakland Bay Bridge carries 251,000 AADT. The Golden Gate Bridge carries 118,000 AADT.
the second widest in San Angelo is Sherwood Way that is now seven lanes
I-55 is eight lanes throughout much of north Jackson.
Let's see ... counting the collector-distributors, you'll find around eighteen-ish lanes (five on each direction of the mainline, up to four on each collector) on I-15 at the I-80/SR 201 interchange.
The largest in my area would have to be I-96 between W. Outer Drive and W. Davison Avenue in the city of Detroit. That portion of Freeway has a total of 12 lanes, which are divided in 3 express lanes and 3 local lanes on each side.
I-80 is 8 lanes wide in most of my town. It narrows to 6 going west, the right lane becomes exit only for NJ 15 NB. It widens to 8 going east. It actually briefly widens to 5 lanes east bound, as NJ 15 dumps 2 lanes on to 80 EB. The fifth lane becomes exit only for my exit. It can be challenging during times of heavy traffic entering from 15, and I'm EB on 80 and trying to exit as I have about 1/4 mile to get over two lanes to be in the exit lane.
I've driven this freeway last weekend. It's the A15/A16, with 16 lanes the widest freeway in the Netherlands.

In the greater Cincinnati area there is one stretch of 10-lane highway on I-71/I-75 in Northern Kentucky near Florence and the I-275 junction. Although, there is currently work being done to widen I-275 in the Northern part of the area. It should be 10 lanes when finished.
South Florida is an interesting conglomoration of three large urban counties of 7 million people who live here year-round. During the "season," which for those of you who do not live here is from about two weeks prior to Thanksgiving until Easter (mid-November to mid-April) and the area's population can jump to 15 million or more.
Nearly all major thoroughfares are 6 lanes wide for travel, one or two left-turn lanes and a right turn lane at every intersection, plus a wide landscaped median. Many "side streets" are also four lanes, also with medians and at least one left and right turning lane for intersections.
Palm Beach County has several 8-lane main thoroughfares, Okeechobee Blvd (FL 704) from downtown West Palm Beach to the suburbs in Royal Palm Beach is almost all paved for 8 lanes. US 441/FL 7 (Range Line Road) has been expanded from 2 lanes to 4, 6 or 8 lanes through West Boca Raton, 30 miles north to its current terminus at Okeechobee Blvd. When I moved here in 1998, US 441/FL 7 was a very narrow 2-lane road between Yamato Road (FL 794) and Southern Blvd. (US 98/FL 80) with wild sugarcane, lots of Australian pines and nearly nothing developed beyond a few farms, religious colonies and a poorly maintained canal following the northbound lane.
Even with our 8-, 10-, 12- and 14-lane sections Interstate 95 from downtown Miami to Palm Beach Gardens (80 miles), the soon-to-be-expanded Interstate 595 from 6 to 10 or 12 lanes in Broward County with HOT lanes, an 8-10-lane Interstate 75 and a widening of the Florida's Turnpike, no road in south Florida is ever wide enough!

Obviously... the Katy Freeway. I travel on it everyday.
Noticed on my morning commute today that I-64 is 14 lanes wide between US-258 and I-664 in Hampton, VA (counting accel/decel lanes).
And US-258 (Mercury Blvd.) is a 10-lane wide street. A very congested 10-lane street.
