removed freeways in North America

[PHLBOS]

Having said that, I've noticed a tendency for the early, 50's-60's-era toll roads to build a trumpet interchange with the surface road by default, whether the traffic count called for it or not.  Some of those early loop ramps were tight; with today's longer trucks, a signalized intersection might actually be safer, especially in areas where it ices up in the winter.  I suspect there was a "mentality" if you will, at the time, that stopping traffic on surface roads with signals was a no-no when it came to freeway access, which also explains all the full cloverleafs with surface arterials from that era, many of which have recently been converted to parclos to avoid weaving motions.

The likely rationale for such a design approach was probably to avoid left-turn conflicts (potential for head-on collisions) and account for future growth (increased traffic counts).  In short, just because the traffic along the road at a dual-trumpet interchange for a toll road isn't at Level of Service E or F (gridlocked) at present; doesn't mean it won't be 20 years down the road.

What about Central Freeway Us-101 it was demolished for re development reasons and quake fears. Central Freeway was supposed to be in close proximity to the Castro and Haight districts. There were maps saying that I-80 was supposed to take the Central freeway or US-40 and US-50 the previous alignments to I-80 in San Francisco.

Cypress freeway was moved to the Port of Oakland when they rebuilt the north end of I-880 in the 1990's. Cypress Freeway used to go through Nelson Mandela blvd. In Oakland prior to 1989.

There was a Colorado Freeway in Glendale, but that was bypassed by the CA-134 Ventura freeway.

The post you quoted already mentions the Cypress viaduct relocation.

Already mentioned in the post you quoted, as well.  (And only the segment north of Market Street no longer exists; the portion from Market to I-80 is still in regular use)

Another rural/suburban relocation: I-70 in Maryland between exits 56 and 59. The old I-70 alignment is now part of MD 144.

This was never a full freeway.

PS: what's with the 1pt iPhone text? I've seen it on multiple people's posts.

That's because too many Tapatalk users never bothered to turn off the setting that adds "Sent from..."  to the bottom of every post, so the mods use the profanity filter to turn the common parts into formatting tags that make the variable part nearly invisible.

That was more so that they only had to build and maintain one toll plaza per interchange. Back when all tollbooths had human collectors, this would significantly reduce operating costs.

No, what he's saying is that the intersection with the surface road was often a trumpet rather than an at-grade.

Ah. Then as later stated, it was likely in anticipation of higher traffic counts, along with a desire to keep from backing up traffic at the toll plazas.

This doesn't quite answer the question, but at least shows the route still in existence.  It's basically is as it always was - a short offramp connector (which manages to have two exits eastbound!)

I think it's amazing how fast freeway removals move.  many of them are so fast that state DOT isn't prepared for it and might even do work to maintain the about to be removed freeway.  With CT 34, obviously ConnDOT didn't know that removal was coming, because there's no need for a flyover like the one they built for a surface street.

It's a question of who's calling what shots. Removing the Oak Street Connector was something the city of New Haven came up with and started clamoring for. ConnDOT wasn't planning for it to happen because it wasn't their idea. So ConnDOT only knew about it once they started getting leaned on to make it happen, it was never in any long range plans and therefore was not considered in any projects prior to it.

As for how fast it moves, well, yeah, it's amazing how fast construction moves when environmental groups favor it and no one tries to sue to stop it.

Add "and when there are no NIMBY's" and it's just as apt...
