Concrete deck and substructure removal on multiple I-95 bridges, including the Vaughn Daggett Bridges over the Penobscot River.
Overview
Select Demo was contracted by New England Infrastructure to perform concrete deck and substructure removal on multiple bridges along the I-95 corridor in Medway, Maine, as part of the Maine Department of Transportation's Initiative for New Decks Essential for Economic Development.
Scope
- Deck removal at Route 157 over I-95
- Deck removal at the Vaughn Daggett Bridges carrying I-95 northbound and southbound over the Penobscot River
- Deck removal at the I-95 northbound and southbound bridges over Route 116
- Substructure removal
Approach
Decks were saw-cut and broken out by excavator over the steel girders, with staged traffic shifts maintaining interstate operations. Hand demolition with hydraulic breakers cleared concrete around bearings and at girder flanges.
