Emergency Bridge Repair – Moodus River Bridge

East Haddam, Connecticut

Services: Transportation Engineering
Clients Served: Government

Loureiro was awarded the contract for this bridge reconstruction project after the Connecticut Department of Transportation issued an emergency declaration and closed the bridge to all traffic because of the condition of the structure. This project exemplifies Loureiro’s design and construction groups – working together as a team to combine our structural design, environmental remediation, and construction expertise.

The DOT advertised this bridge reconstruction as a Design/Build in 2009 – one of the first ever advertised this way – as they needed a very fast-track design/build process.

Loureiro prepared the design plans for this project which included the structural design of the new bridge structure. A cast-in-place concrete strip footing supported on micropiles to support the arch and wingwalls was initially included in the DOT bidding documents. Founding the structure on rock, a design change advanced by Loureiro changed the foundation design by eliminating the need for micropiles – a design choice that helped expedite the construction schedule.
