Description: R-2539B - CRAVEN-PAMLICO COUNTIES LOCATION: Bridge on NC 55 over Upper Broad Creek.
ITEM(S) OF INTEREST: A 12-span link-slab bridge, in which slabs were made continuous of the bents by debonding the slab at joint locations. Observations and Points of Discussion:
Deck had a lot of surface type crazing cracks.
Over the bents, the deck was saw cut and silicone filled.
Lack of tooled contraction joints on 2BMR parapet had resulted in cracks in the parapet.
The bridge skew was set with flood flow direction not the normal flow direction.
The bridge was re-scoped and lengthened to bridge the surrounding wetlands. The skew could have been eliminated for the longer
bridge.
This project demonstrated that in some situations the link slab is a viable alternative to a continuous for live load diaphragm.
