Trumpets with twin parallel overpasses

[briantroutman]

The Bensalem Interchange (US 1) on the PA Turnpike has two parallel, separate overpasses carrying traffic to and from the eastbound lanes.

Do other trumpets have the same arrangement? Were any built that way? (As opposed to this example, which originally had only one overpass carrying both directions, then a second was added later.)

I-95/MA 128 at US 3 is a trumpet with separate overpasses.

[briantroutman]

^ I'm a bit busy today to do research, but I'll take a guess: This was planned to be a full eight-ramp cloverleaf for an extension of US 3 inside the I-95 circumferential, but that extension was cancelled, right?

Did this interchange ever operate as two loops? I can see what appears to be the north-to-north loop, but I can't tell if that's a remnant of a once-functioning ramp or merely maintenance/police access on the unused grading.

Off hand, NY 85 at I-90 is like this.

^ Interesting geometry. Were plans for a longer freeway scuttled here, too?

I-84 at Exit 36 in CT  has an interesting one where the eastbound exit is a left hand exit so the (somewhat) parallel overpasses extend over the eastbound lanes only.

US 10 and US 45 (N).  It was orginally built that way.

In McLean, Virginia, the George Washington Memorial Parkway (National Park Service maintenance, "secret' VA-90005) ends at I-495 just south of the American Legion Bridge over the Potomac River with a trumpet.  Traffic from the Inner Loop I-495 and to the Outer Loop I-495 have always been on separate bridges, perhaps because at one time there were plans for this parkway to continue further upstream to the vicinity of the Great Falls of the Potomac.

The I-75 interchange with M-24/Business I-75 in Auburn Hills, MI is a double trumpet with twin overpasses over both highways:

Kentucky's trumpets do -- including I-71 at I-75, Bluegrass Parkway at I-65, Cumberland Parkway at I-65, Audubon and Green River Natcher parkways at US 60.

The trumpet interchange between I-80 and CA 65 in Rocklin, CA features twin bridges on the 65 overpass.  This is an interesting interchange in that the main movement within the "trumpet" segment south of I-80 utilizes the loop rather than the direct connection due to the topology of the region (there's a stream bed immediately south of the interchange that was deemed too environmentally fragile to be disturbed (which it would have if the trumpet had been configured otherwise).  I lived in the area when the interchange opened in mid-1987 and wondered about its construction details (my cousin, who was interning with Caltrans then while in college, supplied me with the reasons it was built that way).  Commuter traffic heading for north Roseville and Lincoln (and there's plenty these days) must take the 25mph 2-lane loop; while the direct trumpet component sees relatively little use.  For budgetary reasons, it'll probably stay that way for quite some time (a long flyover is a long-term possibility, but not in the near term).

There's 3 in Virginia I know of:

VA 895 ending at I-295. Looks like this one was designed in a way where VA 895 could be extended eastward sometime in the future (I seriously doubt that will ever happen)
https://goo.gl/maps/RPsPKGBWg6A2

VA 288 ending at I-95
https://goo.gl/maps/jmcELx6zPTq

VA 33 beginning/leaving its duplex with I-64. This one also looks like there's room for the road to be extended but I've never heard of any talks about that and I'm not sure why this interchange is designed this way

Since this interchange (and I-69 in Southern IN overall) didn't even exist not that long ago, this one was built this way from the start

I didn't think this was uncommon. I see it when the terminating roadway has a wide median, that for purposes of geometry, is maintained throughout the loop. Two examples off the top of my head in Washington (US-195 @ I-90 in Spokane, and SR-512 @ SR-167/161 in Puyallup):

FWIW, neither of these freeways had any extension plans. They just had wide medians.

Great top picture of 90/195; note the Latah Creek RR bridge going right through the trumpet; that's the big BNSF junction in the area: the right side heads to the Puget Sound (comes out at Everett) via the Cascade Tunnel, while the left goes through Pasco on the way to the Columbia River and Portland.  The Amtrak Empire Builder Portland and Seattle sections split at the Spokane depot about a mile east of the bridge and use the respective branches to reach their destinations.

In thinking about this question, it dawned on me that none of Vermont's trumpet interchanges** have the ramps bridged over the freeway mainline.  In each case, the freeway is bridged over the ramps.

** - Though similar to a "double-trumpet", I'm not counting the US 7/VT 279 interchange complex as a trumpet.

The southeastern US 340/WV 9 interchange on the Charles Town, WV bypass is this way: https://goo.gl/maps/EU5um35Hgtr

Another Southern IN Trumpet, done this way, is in Terre Haute with the US 41/IN-641 Interchange -- and built this way recently, as IN-641 isn't that old of a route

I believe Minnesota only has one trumpet interchange (which does not qualify).

[Ian]

The trumpet interchange along the Maine Turnpike (I-95) at I-195 in Saco has parallel overpasses. It's the only dual-overpass trumpet interchange on the turnpike, and one of two I'm aware of in Maine. The other is along I-295 at exit 28 (US 1 connector) in Brunswick.

[froggie]

I believe Minnesota only has one trumpet interchange (which does not qualify).

Before US 14 was relocated west of Owatonna, the southern I-35/US 14 junction (Exit 40) was a trumpet with dual overpasses.

There are four current trumpets in Minnesota (US 53/MN 169, southern US 52/MN 60, both MN 15/MN 60 junctions), but none of them meet the OP's requirement.

In Central IL between Bloomington-Normal and Lincoln:

Does a Trumpet for a Rest Area count? Also, thru I-55 has the dual overpasses, over the ground-level ramps to/from the Rest Area and I-55 North. Of course, one could argue its not a true Trumpet, since the I-55 South ramps to the Southbound Rest Area parking lot is offset and further south than the I-55 North ramps to the Northbound Rest Area parking lot. It is a single Rest Area for both directions of travel
