Seminary Avenue Bridge

East Coast Concrete Specialties, Inc. was contacted by PDI- Sheetz Construction Corporation to help decide the best method to remove a concrete bridge that was 37” thick concrete. The original bridge was built in 1906 and was 17” thick concrete. The bridge was later raised in elevation by 20”.

The State of Maryland had taken core samples that showed loose and deteriorated concrete. This job had to get done fast with minimal road closure. Concrete precast planks were fabricated for the new bridge to be placed onto the new abutment foundation that was installed outside of the existing abutments.

We began sawing the bridge into sections on a Friday morning using blades up to 92” in diameter. We also core drilled four pick holes each, into the sections to be removed. The cutting and drilling was completed by the next morning so the 150 ton crane could remove these sections. The precast was installed on Saturday, and the bridge was open on Monday.
