Resiliency improvements, NCC, SR299 odessa

The Federal Highway Administration (FHWA) awarded the Delaware Department of Transportation $1,345,500 on August 8, 2025, under the Highway Planning and Construction program (CFDA 20.205) to provide planning and engineering services for the Resiliency Improvements project on State Road 299 in Odessa, Delaware. The project scope encompasses the conversion of the existing SR299 Main Street/Old State Road corridor—located between Front Street and Old Corbitt Road—from at-grade to viaduct configuration. This infrastructure improvement is designed to mitigate flooding events and address sea level rise impacts in the project area.

As a state transportation agency with established federal grant administration capabilities, the Delaware Department of Transportation will manage the planning and preliminary engineering activities required to advance this climate resilience-focused transportation infrastructure project. The viaduct conversion represents a specialized infrastructure adaptation strategy aligned with the FHWA's emphasis on resilience and natural hazard mitigation under current federal-aid highway funding priorities. The formula grant allocation supports Delaware's comprehensive approach to addressing climate vulnerabilities while maintaining critical transportation connectivity within the state's multimodal transportation network.
