Delaware Department of Transportation

Statewide Design-Build Pipe Replacements


In an effort to get through the backlog of locations needing replacement, the Department advertised a contract in late 2016 to replace twenty-eight of these bridge-length CMP’s over a four year period.

The contract will be administered via the design-build contracting method. This means that DelDOT will select a team comprised of a contractor and engineering consultant through an evaluation process that considers both qualifications and price. The team that offers the best value through this process will be awarded the contract.

The twenty-eight locations are statewide and are listed below. The selected design-build team is required to perform public outreach during the design process for each location. This outreach will include updates to the web page for each location. In the meantime, click on the link below to find out background information for each site.



In the late 1970s and early 1980s, DelDOT replaced several hundred short span timber bridges with corrugated metal pipe (CMP) culverts, as shown in the above photo. These were inexpensive solutions to replace aging bridges at the time. However, they have reached the end of their service life and require replacement.
