STATE ROUTE 138 (Palmdale Boulevard)
5th St East to 10th St East Improvement Project
FACT SHEET
BACKGROUND

The City of Palmdale, in cooperation with Caltrans District 7,
proposes to widen Palmdale Boulevard (State Route 138)
between 5th Street East and 10th Street East from 2 lanes to 3

south of Avenue Q from 2 lanes to 3 lanes in each direction.

PURPOSE
The purpose of the proposed project is to:
•Reduce traffic congestion through the Palmdale Boulevard/
Sierra Highway intersection,
•Increase traffic capacity on Palmdale Boulevard and on Sierra
Highway,
•Enhance traffic operations on Palmdale Boulevard and on
Sierra Highway,
•Improve railroad pre-emption, thus improving traffic safety
and reducing vehicle queuing at the Palmdale Boulevard atgrade Union Pacific Railroad and Metrolink crossing between
6th Street East and Sierra Highway.
POTENTIAL IMPACTS
No significant impacts that cannot be mitigated to a level
of less than significant have been identified. The resources
that are being evaluated for the project include: community
impacts, traffic, visual, cultural resources, hydrology and
water quality, hazardous materials, noise, air quality, biology,
and cumulative impacts.
Build Alternative
The Build Alternative proposes to widen Palmdale Boulevard
between 5th Street East and 10th Street East from 2 lanes to 3
lanes in each direction and widen Sierra Highway from 2 lanes
to 3 lanes in each direction between Avenue R and a point 500
feet south of Avenue Q. With this alternative, the existing Class
I bike path which runs along the west side of Sierra Highway
will be extended southerly to connect to Avenue R.
The Build Alternative would enhance safety by providing
improvements to the following existing features:
•Upgrading traffic signal operations at the railroad crossing.
•Installing off-quadrant flashing lights and pedestrian gates on
each approach of the sidewalks crossing the railroad.
•Widening and increasing the height of the median islands at
the railroad crossing to provide safe channelization.
•
Upgrading existing nonstandard pedestrian accessibility
features to comply with current ADA standards.
