Davis County – Mulberry Ave. Bridge Over Carter Creek

The existing bridge was a 69’ x 20’ timber stringer bridge with high timber abutments and timber pile piers which spanned Carter Creek.  The bridge was both structurally deficient and functionally obsolete before being closed during a 2014 flood event.  The flood washed out the roadway behind the abutment and knocked piles out of the pier with a large pile of drift.  The bridge did not meet current hydraulic or loading requirements.  The project consisted of a custom 120’ x 24’ pretensioned prestressed concrete beam bridge with integral abutments and open channel cross section, to eliminate drift-catching piers and pass drift through the opening in the case of future flood events.  The project included approximately 500 lineal feet of approach grading.
