This project consisted of analyzing the existing road surface with a falling weight deflectometer and ground penetrating radar to determine the extent of paving to be left in place and rehabilitated. Coordination with the consultant for the Kilpatrick Turnpike extension was required. This extension crosses over Reno Avenue and has lane / bridge extensions for Interstate 40. There are a total of five new bridges associated with the new turnpike.
The project included three major cross drainage structures for runoff across Reno Avenue. Each of these structures was analyzed using the HY8 computer program to maximize the efficiencies of the cross drains for a 50-year flood with a maximum of one foot of headwater at the intake for the structure. This resulted in the selection of reinforced concrete boxes for the cross drains on Reno. A drainage system was analyzed for the paving slab and curb to prevent water from accumulating on the roadway to obstruct traffic during a rainfall event using the Haestadt Methods StormCad. Emergency traffic would be able to negotiate the road during times of rainfall using the center lanes of the roadbed with the outside lanes containing the storm runoff.
Coordination of the project with local developers resulted in a fifth lane being added west of the bridges of Interstate 40 to Mustang Road. The fifth lane will allow access to the south for commercial and residential development without impeding traffic flow along Reno Avenue.
The project included the following elements:
- Widening
- Grading
- Drainage
- Traffic Signage
- New Construction
- Design
- Utility Relocation
