Overview

The Page Mill Road Expressway Study project identifies improvements to relieve congestion and improve pedestrian and bicycle connectivity along the expressway and at intersections between I-280 and El Camino Real.  

The Page Mill Road Expressway Corridor Study report is now available.

An overview of the study will be provided to the Los Altos Hills Town Council on June 18, 2015; to the Palo Alto City Council on June 22, 2015; and to the Palo Alto Planning and Transportation Commission on June 24, 2015.

COYOTE HILL INTERSECTION ANALYSIS REPORT 

This technical memorandum documents the traffic analysis assumptions, methodology and findings for the Page Mil Road/Coyote Hill Road intersection comparing two potential improvement alternatives to each other and existing conditions. The improvement options are closure of the median gap along Page Mil Road, effectively allowing right-in/right-out access only to/from Coyote Hill Road and signalization of this intersection.

CORRIDOR IMPROVEMENT CONCEPTS

The project team has been working closely with City of Los Altos Hills, City of Palo Alto, Caltrans, and VTA staff for input on the technical analysis, including concepts to illustrate potential project configurations. The concepts are planning level drawings (not design level) to determine technical feasibility, potential right-of-way impacts, a cost estimate for the Plan list, and community acceptability. There are three alternative concepts each for the Page Mill/I-280 interchange improvements and for grade separating the Page Mill/Foothill-Junipero Serra intersection.  A final proposed concept for each of these two locations will be one of the alternatives shown or a hybrid/modified concept based on the analysis of the alternatives and community input.

Traffic Simulations Videos: Using a traffic demand model, traffic flow simulations have been developed for the AM and PM peak periods for each of the alternatives using projected 2025 traffic volumes.  Videos of the simulations have been posted on YouTube (click here).
