Document Description
Caltrans proposes a 0.15-foot Rubberized Hot Mix Asphalt overlay within the project limits. Shoulder backing would be placed along pavement edges. The existing roadway has 11-foot-wide travel lanes with 1-to-2-foot shoulders. The project proposes to widen the roadway with 12-foot lanes near the north side of I street (post mile 1.8) to West Pozo Road (post mile 3.15). Six-foot shoulders are proposed from I Street (post mile 1.8) to West Pozo Road (post mile 3.15). In this segment, sidewalks and curb ramps that meet accessibility requirements would be installed, and shoulders would be widened to provide more space for bicyclists. Existing asphalt concrete dikes would be upgraded to meet existing standards. Culvert inspections have identified seven culverts that need to be repaired or replaced. Two residential culverts and one private driveway culvert would be replaced to accommodate roadside flow affected by the shoulder widening. One traffic count station would be installed. All existing metal beam guardrails would be replaced with the Midwest Guardrail System, the current standard. Right-of-way acquisition is expected for shoulder widening and associated utility relocations.
