Interchanges converted to at-grade intersections

[webny99]

Personally, I do think 10K is reasonable, although sadly, NY gives no consideration to widening - even at volumes much higher than 10K. Four-lane divided non-freeways are exceptionally rare in NY and I would love to have more of them, including one or more four-lane routes to Ithaca.

Rochester > Ithaca is a royal pain. Every time I do it, it seems like you're on backroads forever.

I'm thinking the old Park Freeway in downtown Milwaukee is an example. I remember as a kid it was mostly an elevated freeway and now it's a surface street east of 43.

I don't know what the original section really had in terms of interchanges along it, but I imagine this is an example.

The 4 lane section isn't that long.  If there was a real need for it, it would have been expanded long ago.

California examples:

- I-280 at 4th Street in San Francisco, originally one offramp off of northbound 280, now a full at-grade intersection of King Street and 4th Street
- Tower Bridge Gateway (former Route 275/former US 40 and 99W) at 5th Street in West Sacramento, formerly a partial diamond interchange, now a full at-grade intersection
- Oxnard Boulevard (former Route 1) at Channel Islands Boulevard in Oxnard, converted to intersection in the early 2000s as part of the move of Route 1 to Rice Avenue corridor (which now has an interchange here)

For the last of those, I think you meant Oxnard Blvd at Pleasant Valley Road -- the Oxnard Blvd / Channel Islands Blvd / Rose Ave intersection has been basically unchanged for decades, while the Oxnard Blvd (CA 1 S) / Pleasant Valley Rd / Rice Ave (now CA 1 N) intersection was greatly modified as part of the CA 1 rerouting.

Thanks!

Just made the correction.

A couple of other California examples:

- Washington Street at Junipero Serra Boulevard in Daly City, converted back to regular street intersection in the early 1970s to accommodate I-280 now having an offramp from Washington.

- Melrose Avenue at Colorado Boulevard in Eagle Rock, Los Angeles, was grade-separated with ramps as part of the original Colorado Freeway project for Route 134/Alternate US 66, before that portion of the Colorado Freeway was revamped when it became part of the Ventura Freeway.  (Interestingly, further east, the interchange with Linda Vista Avenue/former Route 11 still remains to this day!)

I don't know what the original section really had in terms of interchanges along it, but I imagine this is an example.

There was a complete interchange around 5th/6th Sts west of the river and then at its temporary end at Broadway east of the river.  The next interchange that was planned to the east was at Prospect/Farwell/Ogden, by the current tram terminal, then it was to curve southward to feed into the Hoan Bridge/I-794 with a street interchange at Clybourn.

The Prospect/Farwell/Ogden interchange would have been the major access to the city's upper east side.

Don't forget the PA Turnpike exit at US-13 in Bristol.  The trumpet interchange was recently replaced with a signalized T-intersection (oddly, a loop road was built on part of the old loop-ramp footprint, at surface level, apparently for official use only.)

I've often said that when turnpike construction was in full swing back in the 50s and 60s, there was a tendency to put a trumpet ramp on the local road even if it really wasn't needed.

I don't remember much about the Park Freeway living in SE Wisconsin as a kid, but a friend of mine who lives on Milwaukee's east side, said the demolition of it really spruced that area up.

Kansas Turnpike Interchange 177 did a similar thing, where it used to have a trumpet connecting to Topeka Boulevard, but it was later replaced with a signalized intersection.  In that case, it seems justified, for the sake of connecting Kansas Avenue to Topeka Boulevard and the Turnpike without building a larger interchange.  Location: https://goo.gl/maps/nQirmMB2UUe1dajK7

A few other local ones, besides the one I mentioned earlier in the thread:

K-7 and Santa Fe Street/135th Street: https://goo.gl/maps/HEd2YkgXeDcs3Vne6

Johnson Drive and Roe Avenue, part of a larger interchange: https://goo.gl/maps/sCrxtu1XyWB1A8xD8

Half-interchange at Roe Avenue and Skyline Drive/48th Street (they might have even moved the whole cross-street for this one): https://goo.gl/maps/jYBk7NNGV4eNY3Uv8

Turner Diagonal and Riverview Avenue (fairly recent): https://goo.gl/maps/TToWZq1EBHoqMwKYA

Turner Diagonal and State Avenue, converted from three-way interchange to four-way intersection: https://goo.gl/maps/YwzTkXkdzgVmy3Lf7

Why do I feel like I'm missing one somewhere else that's local to me?
