Harbor Freeway (SR-110) Construction of Auxilliary Lanes


Caltrans is widening the Harbor Freeway (SR-110) in both directions through Downtown Los Angeles, approximately one-half mile south of the Washington Boulevard underpass to just north of the Wilshire Boulevard overpass, a distance of 1.6 miles.




The Harbor Freeway is a north-south route that runs from Gaffey Street in San Pedro to Colorado Boulevard in Pasadena. The segment that runs through Downtown Los Angeles has not been substantially improved since it was built. It currently handles traffic volumes beyond its design capacity, resulting in significant congestion. Extended periods of congestion affect not only access to Downtown Los Angeles, but also through traffic.



This project will enhance safety and reduce congestion by widening SR-110.

Southbound SR-110 : Widening the 11th Street overcrosing, a portion of the I-10 connector and the merging area at the 8th Street on-ramp which allows motorists to continue onto I-10 without changing lanes.

Northbound SR-110 : The construction of an additional lane on the mainline from Olympic Boulevard undercrossing to 6th Street. The replacement of curb medians and concrete barriers  



Project cost is $55 million. Flatiron West, Inc. is the contractor on this project.


Caltrans has completed installment of median lights at the Olympic Boulevard and Ninth Street undercrossing. The merge shoulder on the southbound SR-110 to eastbound I-10 connector was widened to allow additional lanes. 


Construction began early 2010. Scheduled project completion is spring, 2013.
