Design-Build Statewide Pipe Replacement for BR 1-455 on Deer Run Road

Comment submission has ended. Thank you.

Welcome to the Delaware Department of Transportation's virtual workshop. The goals of the virtual workshop format are to make it easier for the public to view the project information and to reduce the costs involved in traditional public workshops. This is a workshop regarding the replacement of Design-Build Statewide Pipe Replacement for BR 1-455 on Deer Run Road.

Bridge Photos Bridge 1-455 has been identified by DelDOT's bridge management system as being in need of repair. The existing structure consists of two 121" x 85" corrugated aluminum pipe arches with a length of approximately 50 feet. The replacement of Bridge 1-455 has been proposed as part of a statewide culvert replacement contract to replace corroding corrugated metal pipes. The bridge has a sufficiency rating of 97.0 and exhibits some minor deterioration and damage.

Construction Plan The scope of the proposed project is to replace the existing pipes with three round reinforced concrete pipes. The proposed reinforced concrete pipes have an inside diameter of 84 inches and are 72 feet in length with riprap aprons installed at the culvert inlet and outlet openings, extending into the channel bed upstream and downstream. Pipe replacement will be performed under a full road closure with a posted detour.

Bridge Plan, Section and Elevation: In keeping with the Department's mission that includes providing "a safe, efficient, and environmentally sensitive transportation network", the proposed design will limit any impact to the surrounding areas. The proposed structure consists of three 84-inch reinforced concrete pipes that are 72 feet in length. The upstream and downstream embankments and the channel bed at the pipe openings will be protected with riprap aprons. Two 10-foot bituminous travel lanes at a 2-percent slope with grass-shoulders at a 4-percent slope are proposed. An 8-foot clear zone will be established beyond the travel lanes by grading an area of 6 feet (minimum) beyond the shoulders at a slope of 6:1 or flatter.

[Maintenance of Traffic] 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. Temporary closure of Deer Run Road(N466) between Eagles Nest Landing Road(N465) and Gum Bush Road (N51) shall be necessary during the duration of this contract. A detour route has been provided and can be found under [Detour Information] on this project's website.

Right-of-Way 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. Existing right-of-way is 25 feet on either side of the roadway centerline with additional easements upstream and downstream of the existing bridge. Temporary easements shall be utilized at all 4 corners of the project to allow access for all proposed work to the bridge. All areas disturbed within these limits shall be restored to their natural condition upon completion of the work.

A real estate representative will contact any impacted property owners to review the Department's Real Estate process.
