PROJECT STUDY REPORTS
I-5 Parker Avenue & I-5 Lake Hughes Road
Los Angeles, CA
Client: SunCal Companies
SunCal Companies is proposing a new 3,000 home development in
the Castaic area of northern Los Angeles County. As a mitigation measure for the development,
SunCal are required to improve the I-5 Parker Road and the I-5 Lake Hughes Road
interchanges. The existing interchanges are outdated.
Numerous improvement alternatives were developed for the two locations as part of
the development of a Project Study Report (PSR). Due to inadequate vertical
clearance, the existing Parker Avenue overcrossing must be reconstructed. The
alternatives include ramp configuration modifications at both interchanges, local
street widening, and intersection improvements.
Roadway improvements will be completed and approved in both Caltrans and Los
Angeles County right of way. The conceptual design process includes
geometrics, drainage studies, construction staging and traffic management, storm water data
report, signal modification, geotechnical analyses, hazardous waste studies, utility
modifications, and right of way.
