Pioneer Street Rail Overpass

Pioneer Street Rail Overpass

General Contractor: Tapani, Inc | Project Owner: Port of Ridgefield  |  March, 2020 - Q4 2021


In the early 2000s, the Port of Ridgefield envisioned and began its effort to secure the funds required to construct a rail overpass at Pioneer Street. When completed, the overpass will provide safe and guaranteed pedestrian and auto access between downtown Ridgefield and the waterfront, including the port’s 41-acre mixed-use development site.

The Pioneer Street Rail Overpass will provide safe access to and from the waterfront for motorists and pedestrians. The aerial span will connect to the north and south approach roads built by the port earlier in two separate phases. Construction on the final phase began in March 2020. The final phase includes the completed design and City of Ridgefield permitting for the project.

This project required a Bauer BG-40 to drill six, 8' shafts to depths of ~70'. Watch the video below to learn more about this project!
