The Golden State (5) Freeway in Santa Fe Springs will be shut down at intervals over the weekend as part of a project to add lanes to the roadway and reconfigure the Alondra Boulevard bridge.
The driver allegedly hit a pedestrian at Alonda and Holly, near Thompson, and then fled.
Officials said a man was found dead Sunday in La Mirada.
Local commuters were directed Monday to detours following the closure of a portion of Alondra Boulevard in Santa Fe Springs.
Police are on the hunt for a masked robber who attacked a Bellflower store owner with a crowbar Wednesday.
