Project Overview and Significance

The purpose of the proposed project is to reduce congestion, reduce accidents, and improve freeway operation. The project limits on I-15 are from 2.3 miles south to 2.0 miles north of the I-15/215 interchange and on I-215 from 1 mile south to the I-15/215 interchange.

These improvements include the addition of one northbound lane and one southbound lane on I-15 between I-215 and Glen Helen Parkway, where the current freeway is three lanes in each direction. The addition of the new lanes will provide a continuous set of four lanes in each direction between State Route 60 and US Highway 395.

It is proposed to reconfigure the I-15/I-215 interchange and adjacent local interchanges to reduce traffic delays, improve the flow of goods through the region and enhance the reliability of goods headed to and from freight facilities in the Los Angeles Basin, including the Ports of Los Angeles and Long Beach.

Truck bypass lanes also are proposed to help improve traffic flow along this major freight movement route. I-15 is designated a Corridor of National Significance, and this interchange is a critical bottleneck for the region. Adding truck bypass lanes will eliminate the need for slower-moving trucks to weave across heavy, faster-moving automobile traffic to enter the right lanes as they pass through the interchange.

Currently the interchange experiences 1,200 daily vehicle hours of delay at an annual cost of $3.75 million. Without the improvement project, these numbers are expected to increase by the year 2040 to 25,000 daily vehicle hours of delay at an annual cost of more than $80 million.

The interchange was named the highest short-term priority in the Interstate 15 Comprehensive Corridor Study prepared for SANBAG, Caltrans and the Southern California Association of Governments in 2005. Click here for the project fact sheet.

Alternative 3a maintains most of the existing bridge structures, provides route continuity to the south on I-15, provides a truck bypass lane in both directions on I-15 and relocates the southbound Devore Road ramps at I-215 about 1500 feet to the south, at an estimated cost of $323 M- (NOTE: pdf contains 2 pages - maps alt3a_1 & alt3a_2).
