Interchange one direction, at-grade for the other

[Revive 755]

How common is it for a road to have an interchange for one direction while the other direction has an at-grade intersection?  I've found three so far.

* US 20 in Illinois between East Dubuque and Galena:

* US 50 at MO 150 (I think this one is to become a full interchange soon):

* PA 28 at the 40th Street Bridge:

Similar to this one is OR-43 at the west end of the Sellwood Bridge:

M20 j8 near Maidstone - originally the motorway to the north ended with a fork interchange on the A20. When the motorway was extended, they kept the flyover of the A20 forking off, dumped a roundabout at the end of the motorway and built a roundabout interchange over the motorway, as well as a service station.

A32/A27 junction in Fareham - A27 westbound flys over alongside railway viaduct. Flyover extremely dodgy.

http://maps.google.com/maps?ie=UTF8&ll=51.487322,-0.251237&spn=0.005425,0.013733&t=h&z=17

Hogarth Roundabout, London. A316 London-bound has very dodgy temporary (been there nearly 40 years) flyover to A316 north and the A4 into London. Every other movement has to go via the roundabout.

The Kingsway tunnel provides northbound bypass of the area around Aldwych for Waterloo Bridge to Kingsway traffic.

The A35 was originally fully grade-separated, but now westbound traffic has lights at the merge of the ramp from the roundabout and the flyover. Eastbound is free-flowing. A similar thing happens here (with lights on the northbound merge) on the A322 in Windsor http://maps.google.com/maps?&ie=UTF8&ll=51.483621,-0.623624&spn=0.002713,0.004823&t=k&z=17

There's lots of left filter routes, bypassing roundabouts, here but those junctions aren't two level, so I'll ignore them.

US 11 and PA 29 Jct. near Nanticoke, PA
http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Nanticoke+pa&sll=36.597889,-61.083984&sspn=51.197893,114.169922&ie=UTF8&hq=&hnear=Nanticoke,+Luzerne,+Pennsylvania&ll=41.219163,-75.989513&spn=0.011686,0.010986&t=k&z=16

NB 11 has ramps to from 29.

On SB 11 you take a ramp to 29 and through traffic goes on the older alignment, but there's a local lane NB for people living along there.  Traffic travelling to SB 11 (NB 29!) comes off a ramp but has to stop to join up with US 11 SB.

Preliminary work on redoing this one has begun.  The bulk of the work begins later this year.

This one doesn't count since it's just an at-grade intersection with a couple of "free right" movements.  OP is looking for locations where you have a bona fide interchange in one direction.

Which I can only describe as..."weird"...


One that hasn't been mentioned yet....Lake Shore Dr (US 41) at McFretridge Dr in Chicago.

[UptownRoadGeek]

I think this counts.  Earhart Blvd @ S. Broad Ave & Lapalco Blvd @ Destrehan Ave

[Brandon]

Lake Shore Drive (US-41) used to have one of these in Chicago at 47th Street.  The southbound lanes had a typical diamond interchange, and the northbound lanes had a left turn T-type intersection (no signals).  IIRC, it was replaced with a standard diamond in the 1990s.
