The above photos and graphics show the Sunset Boulevard bridge over the 405 freeway in its current state and what it will look like after it is torn down and reconstructed. The key number to remember: the bridge is 90 feet and six lanes wide at present and when rebuilt will be 120 feet and eight lanes wide with higher capacity on- and off-ramps.
The bridge work is part of the Sepulveda Pass Widening Project that is adding a northbound carpool lane on the 405 between the Santa Monica and Ventura freeways.
All lanes on the bridge will be closed between 10 p.m. tonight and 6 a.m. Saturday morning. There are other closures in the area — here’s a list on the project’s Twitter account.
