The Contractors have submitted product literature to the consulting engineer and TDOT for approval of signal equipment. This was completed on November 21, 2009. They are waiting for this product submittals to be approved by both agencies. Delivery of signal equipment takes anywhere from 6 to 12 weeks. Once the submittals are approved, they plan to order the equipment. They suspect the submittals will be approved prior to Christmas. Once the approvals are completed, they plan to schedule their work at the interchange. I suspect that work will start in January and be completed by March 2010.
