Interstate 15/Interstate 215:
Devore
Interchange Reconstruction
Early project development work began in 2007 for the reconstruction of the Interstate 15/Interstate 215 interchange in Devore. SANBAG is working with Caltrans to prepare a project study report and a project report/environmental document for this interchange.

Project Overview & Significance
The project study report and project report/environmental document will study a number of proposed improvements.These improvements include the addition of one northbound lane and one southbound lane on Interstate 15 between Interstate 215 and Glen Helen Parkway, where the current freeway is three lanes in each direction. The addition of the new lanes would provide a continuous set of four lanes in each direction between State Route 60 and US Highway 395. This would allow motorists to travel through the interchange without having to change lanes or lose lanes in the process.
The proposed reconfiguration of Interstate 15 would allow I-15 to be the primary movement for traffic, with I-215 traffic merging and diverging from the right-hand side of the freeway. These improvements would reduce traffic delays, improve the flow of goods through the region and boost access to freight facilities in the San Bernardino Valley and the Victor Valley.
Truck bypass lanes also are being considered to help improve traffic flow along this major freight movement route. Interstate 15 is designated as a Corridor of National Significance, and this interchange is a critical bottleneck for the region. Adding truck bypass lanes would 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.
This project was named as the highest short-term priority in the Interstate 15 Comprehensive Corridor Study prepared for SANBAG, Caltrans and the Southern California Association of Governments.
SANBAG advanced funds from its Measure I 2010-2040 program to begin this early project development work. The widening of I-15 through the San Bernardino Valley and Victor Valley is also a project of the Measure I 2010-2040 and will be advanced at a later date.
Traffic & Truck Data (2007)
- An average of 160,000 vehicles travel each day on Interstate 15 north of Interstate 215; an average of 140,000 vehicles travel each day on I-15 south of I-215.
- Traffic on this section of I-15 has been growing at a rate of 5% each year over the last several years. This is considered extremely fast growth, since a rate of 2% per year is more typical for the region. The rate of growth is expected to revert back to more typical rates following the recent building boom.
- Traffic forecasts predict that more than 250,000 vehicles could be traveling through the area daily by 2030.
- A total of 21,000 trucks travel through this area daily.
- This interchange is the most significant chokepoint on I-15 in San Bernardino County, with traffic queues extending south for more than three miles to Sierra Avenue during the evening rush hour. Friday evening delays are much longer, due to additional recreational drivers bound for Las Vegas and Laughlin.
- Interstate 15 is a key goods movement gateway to Southern California
Engineering & Environmental Work
As part of the project study report and project report/environmental document, technical engineering environmental, traffic and other studies will be completed. These studies, in conjunction with local jurisdiction and public input, will lead to the recommendation of a preferred project alternative for which environmental clearance will be sought from state and federal agencies.
As part of the technical studies, experts will conduct mapping, surveying and studies of traffic conditions, hazardous materials, railroad operations, public utilities, right of way needs, air quality, noise, sensitive plants/wildlife, water quality, seismic issues, drainage and other potential impacts to the area.
Estimated Project Schedule
The project study report and project report/environmental document are expected to be complete by 2011. Final design and development of project plans, specifications and estimates will follow. Pending the availability of funds, construction could begin by 2013 and last about three years.
Estimated Project Cost:
The total estimated project cost is $200 million in 2007 dollars. SANBAG likely will pursue up to half of these project costs through the Proposition 1B Trade Corridors Improvement Fund. Other funding sources that may be available include Measure I, the half-cent sales tax for transportation improvements in San Bernardino County; the State Transportation Improvement Program and the Proposition 1B State-Local Partnership program.
