Airport Blvd Grade Separation Project Overview

Construction Cost Estimate  $19.8 Million
Construction Start January 2014
Construction Completion Bridge expected to open to traffic in mid-May, 2016

The Riverside County Transportation Department proposes to grade separate the current at-grade crossing of Airport Boulevard (Ave 56) with the Union Pacific Railroad (UPRR) tracks by raising the roadway over the railroad and constructing a a four-lane bridge that will span over the railroad tracks and State Highway 111 (Grapefruit Blvd). On Airport Boulevard, the project begins west of Polk Street and ends near the SR-86 eastbound ramps.  To maintain access to Airport Blvd from Grapefruit Blvd and the adjacent properties , Palm St will be extended to the north from the intersection of Airport Blvd to intersect with Grapefruit Blvd.  The residential properties along the south side of Airport Blvd will be accessed by a new frontage road adjacent to the raised Airport Blvd.
