Side by side freeways.

[UptownRoadGeek]

I was just wondering how many examples of interstates or freeways that run directly next to each other or on the same ROW for some distance without actually sharing pavement. Both I-88/I-355 and I-290/I-294 in Chicagoland are the first to come to mind. What other examples of this setup are out there? I guess examples such as the way Atlanta's southern leg of I-85 sits in the median of I-285 or how I-10 and I-45 straddle and weave inbewteen each other for a mile or two in Houston can be included as well.

295 & the NJ Turnpike in the Moorestown/Mt. Laurel/Cherry Hill area.

95 & the Florida Turnpike north of Miami

[SD Mapman]

What about the UT 67 and I-15 stretch north of Salt Lake?

[KEK Inc.]

I-205 and I-84 for about half a mile.  Well, they share ROW with light rail and a bike trail too.

[jp the roadgeek]

I-84 and CT 72 in Plainville.
I-91 and CT 15 in Meriden (both directions of I-91 are sandwiched in between the CT 15 NB and SB lanes.
US 6 and I-295 in Johnston, RI (US 6 follows the c/d roads)
I-81 and I-476 near Wilkes-Barre.

[kj3400]

I-95 and I-895 in Baltimore when they leave the Fort McHenry and Harbor Tunnels respectively.

[Laura]

I-695 and I-83 in Baltimore. When I-83 merges in and out, it maintains its 2 lanes while I-695 maintains its three lanes. You can pass between the two highways freely during the concurrent stretch, but the lane configuration makes it seem like there are literally 2 highways next to each other.

[J N Winkler]

Another example:  I-75 and I-96 in Detroit.

[NE2]

I-85 and old I-85 (SR 13) in Atlanta. Perhaps the only example with an old alignment.

[jeffandnicole]

Oh yeah...how could I forget 295 South & 76 East/42 South. Not the other side though...that shares pavement...for now! I'll revisit this in a few months when it's separated.

[bzakharin]

US 46 of course runs very close to I 80 across the entire state of NJ, but I guess one can argue which parts of US 46 if any are actually built to freeway standards outside the I-95 overlap.

What's not arguable is that US 46 is never right next to I-80.

[Thing 342]

I-85/I-285 south of Atlanta.

I-73/I-85 south of Greensboro.

[1995hoo]

Dulles Toll Road and Dulles Airport Access Highway in Virginia. The configuration is more like an express/local setup, but they're definitely separate roads with different purposes.

I never realized I-295 served Chicago 

Anyway, In Minneapolis, I-35W runs inside I-94 briefly through downtown, then runs parallel to an expressway, I guess you could call it, that goes into downtown. Further south of downtown Minneapolis, I-35W does it again with MN Route 62 in the Crosstown Commons

I-95 and Florida's Turnpike

I-295 and NJTP

I'd count the "downtown exits" of former MN 65, which spurs into downtown, as a full freeway.

[CentralCAroadgeek]

I-580 and I-80 in Richmond after 580 splits off of 80 towards the San Rafael Bridge.

[ARMOURERERIC]

I-805 and CA 15 in San Diego City

[NE2]

Has anyone mentioned I-95 and Florida's Turnpike?

[vdeane]

NY 49 (and part of I-790/NY 5) and I-90.  This would probably be a multiplex were the Thruway not a closed ticket system here.

Arguably I-8 and MX 2D

A-20 and A-40

[Ned Weasel]

Not quite side-by-side, but close: current freeway and future freeway, only a quarter-mile apart, for a distance of 1.75 miles:

To understand the sarcasm, Look back at the very 1st response to the OP's question...

You seem to be right. I could have sworn there were places where you could see on from the other, but all I can find now is when they cross with each other, which doesn't really count.

How about the Garden State Parkway and US 9 from approaching GSP exit 127 to just short of 129?
