If you commute before 6 a.m., you will want to avoid Sunset Boulevard and the 405 Freeway.
Sunset Boulevard is one of the main arteries connecting Westwood and Brentwood. Some 3,500 vehicles pass over the bridge per hour, but drivers will have to take a detour for the next four nights.
"Sunset is very congested the way it is," said Paula Epelbaum, a Brentwood resident. "Right now, it's impossible."
CalTrans is demolishing the bridge and reconstructing it as part of the 405 Freeway-widening project. Crews will make the bridge longer and more seismically sound.
Sunset Boulevard will be closed intermittently between 10 p.m. and 6 a.m.
The $1.3 billion project includes adding a 10-mile HOV (high-occupancy vehicle) lane from the Interstate 10 to the 101 Freeway, realigning onramps and building 18 miles of retaining walls and sound walls.
Westside residents' patience are being put to the test.
"CalTrans is doing a great job, but if there was a way to put more crews and do a massive job to finish it up quicker," Brentwood resident Karim Amiryani said. "A year and a half from now is way too long."
