Construction on the Valley View Ave. interchange project is now 61% complete. As we move forward, we will need to permanently close the existing Valley View Ave. on ramp to southbound I-5. This will allow us to construct a bridge leading to the new southbound on ramp and to complete the new S. Firestone Blvd.

As a result, the existing S. Firestone Blvd. will be closed from a point about halfway between Marquardt Ave. and the bridge, extending down to the current point of closure south of the on ramp. The closure extension will go into effect at 7 a.m., Tuesday, May 26. The new S. Firestone Blvd. will open by 5 p.m. July 10.

Electronic changeable message signs advising of the closure will be in place by Friday morning, May 15.

Traffic will not be able to access the on ramp to southbound I-5 from Marquardt Ave. However, traffic may continue to access southbound I-5 from the Carmenita Rd. or Artesia Blvd. on ramps.

There will be no through-traffic on S Firestone Blvd. between Marquardt Ave. and Artesia Blvd. However, businesses will remain easily accessible from either Artesia Blvd. or Alondra Blvd. via Marquardt Ave.

We will post proper signage and there will be a temporary cul-de-sac for U-turns.

We apologize for any inconvenience, but this will permit us to substantially expedite this portion of the project and move us closer to completion. Map below:

Workers continue to drive piles below ground to construct footings, erect rebar frames for support columns, and build falsework (temporary bridge support) for the second half of the Valley View Ave. Bridge.
