Ramp Jam work to begin


The demolition of the first two Wilshire-405 ramps begins this weekend. There’s no way of sugar-coating it: there will be significant traffic impacts.

That said, the status quo in the area has been pretty much horrible for as long as I can recall — way too many cars competing for space while trying to enter and exit the freeway. The reconstruction of the ramps should greatly improve the way that traffic flows in the area, but there’s no getting around the pain that ramp reconstruction will inevitably cause.

The above video explains the basics and here is the I-405 Sepulveda Pass Improvements project website page that has more info.

And below is the latest construction notice for the week beginning tonight.

  1. I’d love to hear what the expecting impact to the 720 bus in that area will be. That line is already a nightmare during evening rush hour eastbound getting out of Santa Monica. I’m hoping since cars won’t be able to use Wilshire for freeway access it will help alleviate some of the gridlock the bus gets stuck in.

    @LAofAnaheim, I agree. While freeway construction/expansion is necessary to keep things functioning, no amount of it could noticeably alleviate the traffic in LA. The expansion of the driving population grows way to quickly, construction could never keep up. I’d be curious to know the statistic of how many new drivers will be on the road by the time this expansion is complete.

  2. Bryan – isn’t there still traffic on the 101 freeway even with the Red Line? Have you driven in London or New York? There’s still more traffic in those cities than LA. Rail provides an alternative to driving, it will never displace/replace traffic unless other conditions exist (i.e. higher gas prices, expensive parking, congestion charges).

  3. Mark, cclosing the ramps would do more harm than good since the VA and UCLA medical centers are near these exits. AFTER the construction project ends, the traffic congestion should ease like noticed Thursday. If and when the Purple line finishes to the VA campus and beyond, the traffic should be even less since mass transit will take more of the current burden off our LA roadways. (you could even take a folding bicycle on the purple line).

  4. I am sooo glad that I retired from working at the VA Medical Center and not have to put up with all that mess any longer.

  5. It looks like Ramp Jam is already doing the job: the Thursday PM rush found eastbound Wilshire on approach to the 405 a Sunday-driver’s dream. This cyclist found it refreshingly calm, even Zen, at half (or less) the usual capacity. Proof positive that roads are much safer when half of the drivers are scared off the blacktop. Let’s just close those ramps for good.
