Project Description

This project includes the removal of the existing bridge and construction of a new precast arch tunnel. Final ROW plans have been developed at this time. Additional project details include:

  •  This project will replace an existing 7-span concrete continuous and tee beam bridge over an active CSX rail line with an 84’ precast arch utilizing strip footers;
  • The bridge is on a 14-degree skew;
  • The grade is being raised for additional 3 feet of clearance;
  • The project may be a good candidate for CM/GC delivery;
  • An estimated three to four month closure of SR-10 is anticipated at this time. 

Major Challenges & Issues

The success of this project is directly related to it's constructability and controlling costs. There is areas of possible innovation in the retaining walls and how/when they can be constructed. Specific challenges include:

  • Tight right-of-way on both sides with 35-40 foot retaining walls;
  • Project proximity to existing buildings;
  • Construction activities near and coordination with the railroad;
  • The railroad wants the ability to add extra track;
  • Constraints with site access;
  • 15-20 trains per day with no “train schedule” to reference.
