SR-55 between the northbound Dyer Road off-ramp and Dyer Road bridge. This work will require an extended closure of the outside lane and northbound Dyer Road loop on-ramp from 9 p.m., Friday, April 11 to 5 a.m., Monday, April 14.

The northbound SR-55 Dyer Road off-ramp is expected to reopen to motorists by 5 a.m. on Friday, April 11. The extended closure allows crews to complete concrete activities at the off-ramp.

OCTA, in cooperation with Caltrans, is improving 4 miles of SR-55 between I-405 and I-5. The project will improve traffic flow and reduce travel time by adding one regular lane and one carpool lane in each direction. Also, the project will add merge lanes between several interchanges and stripe carpool lanes for continuous access, augmenting safety on the freeway by making merging easier. These enhancements are expected to create a better, smoother driving experience for motorists.
