I-70 Bridge Widening over Conococheague Creek

Washington County, MD

Maryland State Highway Administration

As part of the Maryland Department of Transportation State Highway Administration’s (MDOT SHA) bridge preservation and replacement program, KCI provided construction engineering and inspection services for this $16.5 million bridge widening and rehabilitation project of a dual steel girder structure along I-70 in western Maryland.

The scope included widening the existing bridges in the median, removal and replacement of the bridge deck and structural steel, widening of the existing bridge piers, and repair and widening of existing bridge abutments. During excavation around the existing pier footers, KCI’s inspectors discovered that two of the footers had significant cracking. MDOT SHA deemed this an emergency situation, and a short-term pier stabilization solution was identified and arranged to begin immediately, while long-term solutions were initiated the same day. Our team assisted in coordinating the multiple state agencies required in ensuring the emergency repairs were completed safely and without impact to the construction schedule.
