Today, the Montana offramp from the Northbound I-405 (San Diego Freeway) will close permanently. Here’s the obituary from LA Metro I read while eating lunch. In it, they talk about the rarety of closing freeway offramps, and pose the question: “After all, how often do California travelers witness the disappearance of entire off-ramp?”
The answer is: Quite a bit.
Here are some that I remember, or at least knew about:
- Southbound I-405, Waterford Avenue. This was the sibling of the Montana offramp, on the SB side of the freeway. It was lost shortly before the HOV lane was added SB.
- National/Pico Ramps from I-405. The Santa Monica Freeway, I-10, was built almost 5 years after I-405 was built through West LA. When originally constructed, there were NB and SB offramps at National and at Olympic/Pico. Construction of the I-10 interchange led to the loss of the SB National offramp, and the NB Olympic/Pico offramp.
- US 101 Haskell On-Ramp. Those who travel US 101 know that there are NB and SB offramps for Haskell Blvd, just next to the I-405 interchange. For the longest time, there was also the remnant of a removed on-ramp from Magnolia (between Haskell and Densmore) to US 101.
- Firestone Blvd off I-5. Back in March, one of the few remaining left exits from I-5, Firestone Blvd, was permanently closed as part of the widening in that area.
So what on or off-ramp permanent closures do you remember? I know that there were some in Northern California near where US 101 and I-880 diverge.
