Hover Street Bridge Rehabilitation/Inspection
Longmont, Colorado

City of Longmont, Colorado

The existing two-span, 101-foot long structure over the St. Vrain River was badly cracked, spalled and delaminated. LORIS was contracted to perform an assessment, design rating and construction administration for the 16 year old structure.

In order to meet current design standards, the existing bridge superstructure, consisting of single and double tee girders with a concrete overlay, was completely removed and replaced. The work was performed in three phases of construction to keep four lanes of traffic plus one sidewalk open at all times. The existing abutments were in good condition; however, the expansion joint was moved from the pier to the abutments in order to increase the structure's service life.
