Project Description: Partial Interchange

The project will construct a partial (three-legged) interchange, a WB on-ramp, and EB on-and off-ramps from Lemon Avenue. It will also permanently remove the existing EB off - and on-ramps at Brea Canyon Road. An auxiliary lane from the proposed EB on-ramp to the connector to SB SR-57 will also be constructed.

The existing sound wall along EB SR-60 west of Lemon Avenue will be removed and a new sound wall will be installed along the edge of pavement of the EB off - and on-ramps.

A new traffic signal will be constructed along Lemon Avenue at the new EB ramps. Traffic signal modifications will also be made at the Golden Springs Drive/Lemon Avenue intersection and at the Golden Springs Drive/Existing EB ramp intersection near the Market World shopping center.

The construction of the new ramps at Lemon Avenue will also eliminate the Truck Route designation along Golden Springs Drive between Brea Canyon Road and Lemon Avenue.
