LAND BRIDGE

Chelsea, MA| 2011

This bulkhead was installed to stabilize a shoreline over a major submarine water utility. The existing shoreline was severely deteriorated timber bulkhead, reinforced by batter piles. The new steel bulkhead was driven immediately inshore of the historic timber pilings, after which the timber piles were cut down to the mudline. We worked with marine engineers to develop the design of the bulkhead and z-pile dead-man to create a land bridge between two disconnected marine terminals.

The construction was scheduled and limited to occur outside the time period of flounder mating, which occurs in the adjacent intertidal mud flats.

In order to keep the weight of loaded trucks set back from the bulkhead, guardrails were installed. Wildflowers were planted in the slack space created between the bulkhead and the guardrails.
