As a result of the “No Build” determination on the I-710 Gap Closure, LA METRO retained ADVANTEC on an On-call Highway Engineering Services Contract to mitigate subsequent traffic impacts along Valley Boulevard in the Cities of San Gabriel and Alhambra. Project involves identifying Year 2045 operational improvements to the New Avenue, Del Mar Avenue and San Gabriel Boulevard intersections along Valley Boulevard.

Among the Los Angeles County Metropolitan Transportation Authority’s (LA Metro) current projects is the 57/60 Confluence Project is a three-phase program of improvements consisting of ramp and interchange reconfigurations as well as the addition of auxiliary collector/distributor and bypass lanes to significantly reduce the weaving and the resulting congestion and accidents.

This project consists of the preparation of Plan, Specifications and Estimates (PS&E) for the addition of two high occupancy toll (HOT) Express Lanes on I-105 on an accelerated schedule between I-405 and Central (Segment 1), and also Segments 2 to 3. The project includes approximately 15 miles of widening within the existing right-of-way, involving bridge widenings, new retaining and sound walls, and new toll collection infrastructure, including tie-in to the existing I-110 Express Lanes.
