BR 1-294 on N346, Walther Road over Tributary to Christiana River
Comment period ends June 10, 2017.
Welcome to the Delaware Department of Transportation's Virtual Workshop. The goals of the virtual workshop format are to make it easier for more people to view the project information, and to reduce the costs involved in the traditional public workshops. This is a workshop regarding the replacement of Bridge 1-294 on Walther Road over the Tributary to Christina River, South of Old Baltimore Pike in New Castle County.
[Location Map] Bridge 1-294 has been identified by DelDOT's Bridge Management section as being in need of replacement. The bridge is located on Walther Road over the Tributary to Christina River, South of Old Baltimore Pike in New Castle County.
[End Elevation] | [Corrosion of Pipe 1] | [Section Loss] Bridge 1-294 consists of two corrugated metal pipes that have been in place for approximately 30 years. The headwalls and wingwalls consist of sacked concrete riprap. The stream channel is straight and fairly well stabilized.
[Bridge Plan & Section] As seen on the Bridge Plan, Section and Elevation sheet, DelDOT proposes to replace the two existing metal pipes with a precast reinforced concrete box culvert. The choice of precast (built off-site) over cast-in-place (built on-site) was due to the surrounding environmental factors and number of residents living close by the structure. The new bridge will be slightly shorter than the existing bridge, due to the flared wingwalls that are about 14 feet in length. The road geometry will not change. Also, in place of the guardrail, two wooden fences will be installed on either end of the bridge on top of the headwall for wingwall protection as well as pedestrian safety. Additionally, riprap will be placed into the streambed and along the wingwalls to protect the proposed bridge from scour and erosion of the stream channel. This work should take approximately 30-60 days to complete and is scheduled to occur in Summer 2019.
[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.
DelDOT will be maintaining a full vehicular detour with a phased pedestrian detour. The phased pedestrian detour will be ADA Compliant with safety fences and barriers throughout the construction zone. Phase 1 will close the East side of Walther Road. Pedestrians travelling from Barrett Run Road will need to cross at the intersection and continue on Walther Road up to the intersection of Cedar Ridge Court where they can cross back over. Phase 2 will close the West side of Walther Road. Pedestrians travelling from Barrett Run Road can still cross at the intersection on Walther Road, but they will be using a temporary curb ramp as the existing curb ramp will be replaced. The pedestrian signal will not be in service during this phase so pedestrians are to be cautious while crossing the street. Pedestrian crossing signs and detour signs will be clearly shown at all times during both phases in order to safely guide pedestrians to their destination.
