Workers completed construction of falsework (temporary frame support) for the next section of the second half of the bridge. We continue erection of support columns for the new Valley View Ave. on ramp to southbound I-5 and demolition of old Firestone Blvd. Photos below from May 27:

The Valley View Ave. on ramp to southbound I-5 permanently closed at 7 a.m. on Tuesday, May 26. This will allow us to construct a bridge leading to the new southbound on ramp and to complete the new S. Firestone Blvd.

The existing S. Firestone Blvd. is closed from a point about halfway between Marquardt Ave. and the bridge, extending down to the standing point of closure south of the on ramp. The closure will remain in effect until 5 p.m. July 10. At that time, the new S. Firestone Blvd. running under the Valley View Ave. Bridge will open to through traffic between Alondra Blvd. / Marquardt Ave. and Artesia Blvd.  

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. during the closure. However, businesses will remain easily accessible from either Artesia Blvd. or Alondra Blvd. via Marquardt Ave.

Proper signage is in place and there is a temporary cul-de-sac for U-turns.

This will allow us to expedite this portion of the project and move us closer to completion. Map below:
