On May 21st, the Warwick City Council approved the contractor selected to repair the causeway at Salter Grove with a $200,000 budget; namely, Narragansett Dock Works (NDW) in partnership with GZA GeoEnvironmental, Inc.
NDW plans to install a prefabricated concrete box culverts at the sites of the displaced footbridge near the breakwater and the existing plastic culverts. The new culverts may be sized approximately 5 feet wide and 4 feet deep to maintain water flow between the north and south sides of the causeway, and to act as bridges.
Depending on the available funding, the elevation of the causeway path may be raised to prevent overtopping during higher tides, and thus provide safer passage for pedestrians.
Permits will be required from the Coastal Resources Management Council, the Rhode Island Department of Environmental Management, and the US Army Corps of Engineers before construction can start, hopefully in late summer.
