Project Overview:
HBG Flatiron
provided design/build services on the $46.6 million Sagadahoc
Bridge, a new segmental structure connecting the towns of
Bath and Woolwich, Maine. Completed in July 2000, this structure
was Maine Department of Transportation's first design/build
project.
Project Features:
3,000-foot-long precast segmental structure spanning the
Kennebec River.
Four lanes for vehicular traffic, bike lanes, and a pedestrian
sidewalk
3 approach spans, constructed of post-tensioned, cast-in-place
concrete box girders, total 1,044 feet
6 main spans over the river, varying from 203 feet to the
record-breaking 420 foot span over the navigational channel,
are constructed of precast concrete box girder segments erected
in balanced cantilever fashion
Barge-mounted cranes erected the 201 segments that were manufactured
in a riverfront casting yard near the construction site
Foundations consist of seven piers located in the water on
8-foot diameter drilled shafts socketed 15 to 20-feet into
rock
