Virtual Workshop:

Blackbird Station Road over Blackbird Creek (BR1-438)

The comment period has ended. Thank you!

Welcome to the Delaware Department of Transportation’s virtual workshop. The goals of the virtual workshop formats are to make it easier for more people to view the project information, and to reduce the costs involved in traditional public workshops. This is a workshop regarding Bridge 1-438 which has been identified by DelDOT’s bridge management system as being in need of repair. The bridge is located in a rural area on Blackbird Station Road over Blackbird Creek.


Bridge Photos

This project consists of two corrugated metal pipes that are encased in a concrete sack riprap headwall. The pipes have active corrosion with measurable section loss. The corrosion has resulted in a loss of section over the length of the pipes. Although the pipes are safe to carry normal traffic at this time, the condition of the existing pipes warrants a full replacement of the structure. The concrete sack riprap headwall will need to be removed at both ends of the bridge

[Construction Plan] As seen on the plan sheet, DelDOT is proposing to replace the existing corrugated metal pipes with precast, prestressed, adjacent box beams on stub abutments. Additional work will include placing riprap in the stream for scour protection, removing the concrete sack riprap headwall, replacing secondary drainage pipes with 18” reinforced concrete pipes, replacing guardrail, and reshaping the channel and side slopes.

[Plan Elevation] In keeping with the Department’s mission that includes providing “a safe, efficient, and environmentally sensitive transportation network…” DelDOT is proposing the replacement of Bridge 1-438. The new bridge is designed using guardrail on the downstream and the upstream side of the bridge.

[Detour Plan] Because of the nature of the work and DelDOT’s commitment to safety of the public, a portion of the roadway will be closed for the duration of the project. As can be seen on the Detour Plan, motorists heading northwest on Massey Church Road towards Blackbird Station Road will take Blackbird Forest Road to North DuPont Highway to Summit Bridge Road to Ratledge Road to Dexter Corner Road to Blackbird Station Road. Motorists heading east on Blackbird Station Road will take Dexter Corner Road to Ratledge Road to Summit Bridge Road to South DuPont Highway to Blackbird Forest Road.

[Construction Plan] Although we strive to perform as much of our work within our existing right-of-way as possible, sometimes the nature of the work requires a larger area than what is provided, as is the case for this project. Minor easements will be required from the adjacent property owners to complete this work. Permanent easements will be required for the placement of the riprap in and around the stream. The riprap will be buried and covered with streambed material (in the stream) or topsoil, grass seed, and mulch (stream banks). Temporary construction easements will be needed beyond the permanent easements for the placement of sandbags so that the in-stream work can be completed and for the tie-in grading. These areas will be restored to their natural condition upon completion of the work. A real estate representative will contact the affected property owners shortly to go over the Department’s Real Estate process.
