Overview
Caltrans began construction at the end of December 2007 on Phase 2 of the Interstate 215 (I-215) widening project
from Orange Show Road to Rialto Ave., and serves as the lead agency for this $89 million section of the freeway-widening project. MCM Construction was awarded the contract on December 14, 2007. Phase 2 is scheduled for completion in 2010.
In the first 15 months since the beginning of the project, the following work has been completed:
- Construction of two new on-ramps and two new off-ramps at Mill Street
- Constructed one-half of the new Inland Center Drive Bridge
- Widened the northbound Orange Show Road off-ramp
- Constructed a new center median
Work to be completed over the next year:
- The completion of wider bridges at Warm Creek and Lytle Creek
- The completion of the Inland Center Drive Bridge
- New on- and off-ramps at Inland Center Drive
- New northbound on-ramp at Orange Show Road
- Two new lanes, one carpool and one mixed flow, on the freeway
- Completion of the widening of Mill Street
Caltrans will serve as the lead agency for construction on Phase 4 of the I-215 Widening Project spanning from Massachusetts Avenue to University Parkway. The $139 million contract was awarded to MCM Construction in November 2009. Funding is provided by State, Local and Prop 1b. Construction began in January 2010 with the closure of Highland Avenue on- and off-ramps.
Work in this phase consist of:
- Reconstructing the bridges at Massachusetts Avenue, Highland Avenue and 27th Street
- Connectors at I-215/SR-210
- Southbound auxiliary lane from University Parkway to the I-215/SR-210 interchange
- New northbound general-use lane
- Local street and drainage improvements
- Addition of soundwalls and aesthetic improvements.
The estimated completion date of this project is Summer 2013.
The entire project will expand and upgrade the I-215 from Interstate 10 to University Parkway. This estimated $800 million project has an expected completion date of 2013. Caltrans has partnered with San Bernardino Associated Governments (SANBAG), the Federal Highway Administration and the City of San Bernardino to complete improvements to the corridor.
Nearly 174,000 motorists travel daily through the Phase 2 segment and it is projected to reach almost 220,000 by the year 2030. Improvements to the I-215 will aid in relieving congestion, improving access to the freeway and local streets and will improve safety by eliminating fast lane entrances to the I-215.

SANBAG completed work on the Fifth Street Bridge (Phase 1) in November 2008, six months ahead of schedule. For general information relating to the I-215 Improvement Project visit the SANBAG website at www.sanbag.ca.gov/215
