The eastbound ramp off of Seventh Street to the northbound 405 and 605 freeways will close at 11 p.m. tonight (Friday) and reopen at 5 a.m. Saturday as a one-lane road.
That configuration will remain for the next year to allow the construction of a new 405-to-605 carpool connector. It is part of the multi-year project to add and connect carpool lanes through the I-405/I-605/SH22 interchange on the Los Angeles and Orange counties border.
In late July, the connector between Seventh Street (SH22) and the northbound 405 will be closed completely. It will be rebuilt over the next year to accommodate the carpool lanes.
The recommended detour takes traffic from Seventh Street up Studebaker Road to the northbound 405 onramp near Atherton Street.
