Diamond Bar : A Promise From Caltrans

An official of the state Department of Transportation assured residents Tuesday that if a project to ease traffic problems on the Pomona-Orange freeway interchange causes more noise, the agency will build a sound wall.

Speaking before the City Council, Wally Rathbart, a supervising transportation engineer for Caltrans, said the agency is considering projects to build an elevated lane for high-occupancy vehicles and a collector road to help cars avoid a difficult merge at the interchange of the Pomona (60) and Orange (57) freeways.

Rough estimates for the projects are $150 million for the high-occupancy lanes and $33 million for the bypass road, Rathbart said.
