Document Description
The Riverside County Transportation Department (RCTD) is proposing to widen the existing AC pavement from 18 ft to 24 ft on the south half of Main Street from TaylorStreet to Michigan Avenue to accommodate two 12 ft wide travel lanes. In addition, curb, gutter and a 5 ft wide sidewalk would be installed which would require the elimination of on-street parking along the south side of Main Street. A 13 ft wide median with a 6 ft high fence would also be constructed. The existing catch basins along the south side of Main Street would be relocated and rebuilt along with the relocation of electrical power poles. Handicap access ramps would be installed at Sanrive Avenue and Michigan Avenue. In addition, a traffic signal at the intersection of Main Street and Michigan Avenue is also included in the project but will be constructed at a later time.
