Interstate 215 California
Interstate 215 provides access to the fast-growing communities of the Inland Empire (Riverside and San Bernardino Counties). The commuter freeway joins a number of cities including Murrieta, Menifee and Perris with March Air Reserve Base and Moreno Valley south of Riverside. A 4.5 mile section coincides with California 60 (Moreno Valley Freeway) northwest to the end of the Riverside Freeway (California 91).
Turning northeast from California 60 and 91, I-215 continues to Grand Terrace and San Bernardino, where it meets I-10. Passing west of Downtown San Bernardino, I-215 begins a gradual westerly shift to Devore and the merge with I-15 south of Cajon Pass.
Interstate 215 in California was originally U.S. 395 between Murrieta and San Bernardino. Signed as Interstate 15E in the 1970s, Interstate 215 was completed by the 1990s. California 215 along the non-freeway (expressway) sections was eliminated with the completion of the freeway between California 60 and California 74.
The long standing bottleneck along Interstate 215 at the late 1950s-era cloverleaf interchange joining the freeway with SR 60 west and SR 91 south in Riverside was addressed with a $317 million upgrade underway from 2004 to 2008. Reconstruction widened five miles of freeway and replaced the loop ramps previously joining I-215 north with SR 91 south and the I-215 southbound mainline movement onto SR 60 east. 11 bridges were built, with the tallest flyover topping out at 90 feet. A half mile section of the SR 91 freeway was raised by 30 feet as well.1

The Interstate 215 Widening Project added a general use and carpool lane to Interstate 215 between I-10 and SR 210, and auxiliary lanes from 5th Street to SR 210 and northbound from SR 210 to University Parkway (Exit 48). The $647 million project also reconstructed all bridges along the 7.5 mile stretch and improved the interchange linking I-215 with SR 210 in San Bernardino. Left exits and entrance ramps were relocated to the right during the January 2007 to 2013 project. The new flyover from I-215 north to SR 210 west opened in December 2011. The connector from SR 210 east to I-215 south followed in July 2012.2
Completed in mid-2016, the $324 million Devore Interchange Project at the north split of I-15/215 added an additional general use lane in each direction, constructed 18 bridges and reconnected Historic Route 66 between Kenwood Avenue and Devore Road / Glen Helen Parkway. Two miles of truck bypass lanes were added in each direction to eliminate slower weaving truck traffic due to the area grades. Associated work improved I-15 north through Cajon Pass at a cost of $121 million. Work at both areas got underway in mid-2013 as design-build projects. It included upgrading local ramp interchanges, and replacing the two outside lanes in each direction of Interstate 15 with new concrete between Kenwood Avenue and a point two miles south of U.S. 395. Additionally provisions were made along the 12-mile stretch for the potential addition of carpool or tolled express lanes.3,4
