Replace Bridge #99 Over New Hope Creek on SR 1723, Orange County, NC

The purpose of this project is to replace Orange County Bridge No. 99 over New Hope Creek on S.R. 1723 (New Hope Church Road), which is functionally obsolete. Bridge No. 99 is 105 feet long. The replacement structure will be a single span, 39-inch precast concrete box beam, approximately 105 feet long with 4-foot deep caps providing a minimum 30-foot, 6-inch clear deck width. The proposed bridge will include two 11-foot travel lanes with 4-foot, 3-inch horizontal offsets. The bridge length is based on preliminary design information and is set by hydraulic requirements. The roadway grade of the new structure will be approximately one foot higher than the existing structure due to hydraulic requirements. The approach roadway will extend approximately 241 feet from the west end of the new bridge and 251 feet from the east end of the new bridge. The approaches will be widened to include a 30-foot pavement width providing two 11-foot travel lanes with 4-foot paved shoulders. The roadway will be designed as a Local Road using Sub-Regional Tier Design Guidelines with a 55 mile per hour design speed. Traffic will be detoured offsite during construction (Figure 2) while Bridge No. 99 is replaced on the existing alignment (Figure 3). The offsite detour for this project will include S.R. 1009 (Old N.C. 86) and I-40. Up to a 6-month duration of construction is expected on this project. The Combined MBE/WBE Goal for this project is 3.5 %.
