Vernon Avenue at the Interstate 10 (I-10) Interchange to improve traffic operation as well as improve bicycle and pedestrian access along Mt. Vernon Avenue through the interchange. The Mt. Vernon Avenue Interchange on I-10 is in the City of Colton in San Bernardino County. The project limits along I-10 begin at the 9th Street (St.) Interchange Post Mile (PM) R22.7 to the west and end at the I-215 Interchange PM R24.3. The project area extends along Mt. Vernon Avenue approximately 540 feet north of the existing freeway centerline and approximately 640 feet south of the existing freeway centerline at the Union Pacific Railroad (UPRR) bridge overcrossing. The existing Mt. Vernon Avenue, through the interchange has four striped lanes, which transitions to three striped through lanes north of the eastbound ramps. The Build Alternative (Preferred Alternative) will accommodate four continuous through lanes through the interchange, two additional left turn lanes in the northbound direction, and bike lanes in both directions. The Mt. Vernon Avenue overcrossing structure will be reconstructed to accommodate the widening on Mt. Vernon Avenue and the future widening of the I-10 freeway to its ultimate configuration. The City of Colton has a separate project which will widen Mt. Vernon Avenue from two through lanes to four through lanes from the I-10 eastbound ramps to approximately 300 feet south of the intersection. This project will further widen the southern leg of the intersection to accommodate a northbound dedicated left turn lane to E. Mission Street. North of the bridge, the existing five-leg intersection connecting Mt. Vernon Avenue and East Valley Boulevard to the I-10 westbound on-ramp, would be realigned with exclusive turn lanes, signalization, and signage improvements incorporated to improve traffic operations. The existing westbound on-ramp and eastbound off-ramp are proposed to be modified to accommodate the wider and taller bridge structure. The project also addresses bicycle and pedestrian modes of travel. Specifically, it would upgrade bicycle access from Class III to Class II bike lane with striped buffer in each direction through the interchange. For pedestrians, it would add a sidewalk on the northeastern side of the bridge and address Americans with Disabilities Act (ADA) access with up-to-date curb ramps. Improvements to the Mt. Vernon Avenue at the I-10 Interchange will be funded by San Bernardino County Transportation Authority (SBCTA) and the City of Colton as part of the Measure I Program. The project is part of the Valley Interchange Program identified in the Measure I Ordinance approved by San Bernardino County voters in 2004.
