SR-57/60 Interchange Improvement Project



The SR-57/SR-60 Interchange Improvements will stretch from just south of the northbound SR-57/SR-60 merge to eastbound SR-60 and south of the Golden Springs Drive overpass and along a portion of Grand Avenue from the City of Industry to the City of Diamond Bar. This is a Caltrans District 7/Los Angeles County Metropolitan Transportation Authority (Metro) sponsored project.

DLCE is currently providing engineering services in preparation of Plans,
Specifications and Estimate (PS&E).  


Our engineers are providing civil engineering support services including cost estimating, quantities, civil engineering plan production support, and CADD design support. We make sure all of our work is in accordance with state and federal standards and requirements.
