The replacement of the James Street Bridge in Newport, DE, addressed critical safety, environmental, and community needs while maintaining access to the Newport Industrial Park.
Originally constructed in 1929, the aging single-leaf bascule bridge had reached the end of its service life and was determined to be structurally deficient, impacting more than 4,500 vehicles crossing the Christina River each day. To support local business and enhance safety, the Delaware Department of Transportation (DelDOT) contracted KCI to provide construction management and inspection services for a new five-span, 394-foot bridge.
Throughout the design and construction phases, the team employed innovative solutions to mitigate various environmental and technical challenges. One of the most critical concerns was protecting New Castle County’s 72-inch Christina River Force Main, a vital sewer line where any disturbance could have caused severe impacts. Strict exclusion zones and precision monitoring ensured safe progress within predetermined boundaries, while other complexities such as poor soils, tidal conditions, adjacent wetlands, and nearby historic and regulated sites required additional coordination. Despite these obstacles, the team worked closely with more than 70 businesses to ensure uninterrupted operations and minimized disruption to the local area.
The completed bridge now features two travel lanes, wider shoulders, and a 10-foot shared-use path for pedestrians and cyclists. In addition, an increased vertical clearance improves navigation on the Christina River, and durable prestressed concrete beams promise a 100-year service life. Architectural details reflecting the character of the area help to match the bridge with the surrounding topography, constituting the landmark as a fully integrated part of the community.
