Upcoming Long-Term Closure Eastbound SR-91 Loop On-Ramp Expected to Close July 7
The long-term closure of the eastbound SR-91 loop on-ramp from southbound Lakeview Avenue is now expected to close as early as 9 p.m., Monday, July 7, for approximately two years. This closure is required for crews to demolish and reconstruct a retaining wall on eastbound SR-91 beneath the existing bridge and to construct an abutment for the new bridge.
Motorists traveling southbound on Lakeview Avenue will be directed to access the eastbound SR-91 using Imperial Highway.
Detour signs will be posted in advance. Motorists are encouraged to plan ahead before traveling through the area.
