Brunswick Bridge Superstructure Replacement
A BridgeNY funded project, HVEA provided the design and construction inspection services for the superstructure replacement of the Brunswick Bridge. The Brunswick Bridge is a two span (94 feet each) steel girder bridge with a 26-foot deck roadway width. The bridge was deteriorating rapidly and had a 3-ton load posting with one lane open to vehicles. The structure had an open grate drainage adjacent to the exterior girders which exposed them to water and road salt leading to deterioration throughout the spans.
HVEA provided the preliminary and detailed design for the full superstructure replacement including new bearings and minor abutment/pier modifications. The new superstructure has a continuous “jointless” concrete deck over the pier to eliminate leaking and improve drainage, specifically road salt. The design also included a wider bridge deck and shoulders to accommodate all modes of transportation and improved shared-use of the roadway.
Environmental considerations were a critical component of this project as it is subject to both NEPA and SEQRA review. Also performed assessments for endangered species, mussel survey and archeological and historic resources which were coordinated through the NYSDOT. Extensive permitting was also required as the Shawangunk Kill is a Class B stream. Permits included: Article 15 Stream Disturbance permit, Water Quality Certification and ACOE permits.
