CHURCH STREET BRIDGE

DEMOLITION and BRIDGE SUBSTRUCTURE

     
This wrecking ball (a very heavy weight) was used to help pull down the old bridge.   Here is a view of the bridge area at the road level with the old bridge removed.

 
This large impact drill assisted in breaking up the road surface and old concrete.   Here is a view from the side with the old bridge removed.
 
A 185 ton crane was used to place the eight sections of the box culvert. The eight sections weigh a total of 28 tons. The box culvert was manufactured in Telford, PA. The box is made to withstand 6000 psi (pounds per square inch) or force.   The substructure is a single cell precast concrete box culvert. Weep holes prevent hydrostatic pressure from collapsing the box structure. Around the box, filtered stone is used to fill in the area between the old abutment and the new box culvert.
