State Route 90 San Pedro Bridge Replacement

The first phase of reconstruction on the San Pedro River Bridge on SR 90 in Cochise County was completed on March 29, 2103, when the newly constructed eastbound side of the bridge was opened to traffic.

Construction activities on the $6.2 million project in the San Pedro Riparian National Conservation Area will be on hold until Oct. 1, 2013, to avoid disrupting the migratory bird nesting season. During the six-month shutdown, two-way traffic will resume on SR 90 through the project area without use of the temporary construction signal that controls traffic sharing a single lane during construction.

When work resumes in the fall, traffic in both directions on SR 90 will share the eastbound lane through the project area while crews reconstruct the westbound lane. The traffic signal will be used during the final six months of construction and delays of eight minutes will be common around the clock until the project is complete in spring of 2014.

The San Pedro River Bridge on SR 90 is an important connection along the primary corridor between the communities of Sierra Vista, Tombstone and Bisbee. The old bridge, constructed in 1955, is being replaced by a new structure featuring wider traffic lanes with shoulders that meet current standards and provide adequate space for vehicles, including emergency responders, bicyclists and pedestrians.

This project will increase in width of the highway bridge from the current 26 feet to 44 feet and will feature 12-foot traffic lanes in both directions and 10-foot shoulders.
