Virtual Workshop #1
The comment period for Workshop # 1 - Red Mill Road over Tributary to White Clay Creek (BR 1-239) 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 the replacement of bridge 1-239 on Red Mill Road over a Tributary to White Clay Creek, East of Newark in New Castle County.
[Location Map] Bridge 1-239 has been identified by DelDOT's Bridge Management Section as being in need of replacement. The bridge is located on Red Mill Road over a Tributary to White Clay Creek, East of Newark, in New Castle County.
[Upstream Elevation] Bridge 1-239 is currently two corrugated aluminum pipes. The pipes project straight out from the earth and seem to be slightly compressed under the vertical pressure. The stream channel is straight and clean with some rocks in the channel and spotted bank failure upstream and downstream.
[Corrosion of pipe & perforations]. The aluminum pipes at this location have been in service for over 40 years and are deteriorating on the inside and outside of the pipe. Both pipes have clearly visible holes in them throughout and are damaged at the inlet and outlet from floating debris. Rust scale in the bottom two feet of the pipe is heavy and sediment has built up inside of them. The loss of section in the pipes along with the other visible damages will eventually lead to the inability of the pipe to function as it was designed to.
[Bridge plan, section and elevation:] As seen on the bridge plan, section and elevation sheet, DelDOT proposes to replace the existing structure with a precast concrete box culvert. The decision to choose precast (or built off-site) was chosen over cast-in-place (or built on-site) due to the high traffic volume on Red Mill Road. Using precast sections for the box culvert will allow it to be constructed much quicker than if the concrete is poured on site. Other work that will be performed on this project includes minor reconstruction of the approach roadway and sidewalks,relocation of drainage pipes, and placement of riprap in the stream channel and sideslopes to prevent erosion. This work should take approximately 2 to 4 weeks to complete and is scheduled to occur during the Spring of 2017.
[Detour Plan] During construction, the road will have to be closed in order to perform the proposed work. as you can see, a temporary detour has been planned to accommodate the traveling public.
[Detour map] This map more clearly demonstrates the route that thru-traffic will take during the temporary road closure. Motorists will be given advance notice of this closure on Salem Church Road, SR 4, Harmony Road, Ruthar Drive, Capitol Trail (SR 2), Polly Drummond Hill Road, and Red Mill Road. From the north side of the bridge traffic will be directed to make a right turn onto Harmony Road, then right onto SR 4,and right again onto Salem Church Road, which will direct traffic left onto SR 273. From here traffic will be directed along SR 273 until it meets Ruthar Drive, where traffic will be directed to make a right turn. The same route will be taken coming in the opposite direction from the Salem Church / SR 273 intersection, however, from directly south of the bridge a different detour will be used. From just south of the bridge traffic will be directed to take a left turn onto Ruthar Drive, then left onto Harmony Road, and left again onto Capitol Trail (SR 2). In addition to the detour for vehicle traffic, a pedestrian bypass will direct people walking this route through the work area on a designated and protected path.
[Construction Plan] Although DelDOT strives to perform as much of the work as possible within the department's existing right-of-way, sometimes the nature of the work requires a larger area than what is provided. That is the case for this project. As can be seen on the plan sheet, permanent and temporary easements will be needed from adjacent property owners in order to complete the work. Temporary easement will be used to allow the contractors to install stream diversions and repair homeowner driveways. A permanent easement is used on the downstream side of the bridge to allow for the placement of riprap. The riprap will be buried and covered with streambed material in the stream, or topsoil, grass seed, and mulch on the stream banks. All disturbed areas will be restored to their previous state upon completion of the project. A real estate representative has already been in contact with the affected owners to explain the department’s real estate process.
