Bridge 1-377 on Choptank Road over Back Creek, Design-Build
Owner: Delaware Department of Transportation
Location: New Castle County, DE
Expertise Provided: Survey, Highway, Structures, Environmental, Stormwater, Inspection

The project consisted of redesigning and upgrading an existing substandard single-lane bridge and roadway approaches in order to satisfy current design criteria.  Design included a precast concrete arch structure with bridge parapets finished with a stone masonry veneer.  The new two-lane approach roadway and bridge provide significant improvement in sight distance and overall safety.  Century was tasked with providing a complete Design-Build package, including all permit coordination, right-of-way acquisition, archeological investigation, utility relocation coordination, public workshop coordination, and inspection.

Challenges Encountered:
  • Achieving DelDOT’s first highway Design-Build contract, marking a new era for DelDOT by awarding a construction project based on a firm’s qualifications, design and schedule, rather than strictly low bid.
  • Providing a complete Design-Build package, including all permit coordination, right-of-way acquisition, archeological investigation, utility relocation coordination, public workshop coordination, and inspection.
