Project Description

Wickford Junction, an MBTA Station on Amtrak right-of-way in North Kingstown, RI originally operated from 1844–1981. In 2011, following decades of local efforts to reopen the station, ground was broken on the new Wickford Junction project. The project would be built as a public-private partnership between RI DOT and the developer.

The T-WALL Retaining Wall System was preferred by the engineer, GZA GeoEnvironmental, Inc., as well as the track owner, Amtrak, to support the station tracks running adjacent to wetlands. Both GZA and Amtrak were familiar with T-WALL and its many advantages, having used it on several previous projects. Railroads prefer T-WALL due to its heavy-duty, corrosion-free properties.

The project benefited from using T-WALL as the system was able to maintain the tight right-of-way restrictions and avoid encroachment into the adjacent fragile wetlands. Bearing capacity was also a concern due to the wetlands, and geopiers were installed and easily compatible with the T-WALL structure.

The contractor, Manafort Brothers, felt T-WALL installed very well and was able to maintain their schedule. Following completion of Wickford Junction in 2011, RI DOT received two project awards. Amtrak representatives visiting the site were also pleased with the final T-WALL product.
