According to Corum, at least ten portable message signs will be used throughout the life of the project, warning drivers of the upcoming construction. Some of those signs will be posted as far as five miles out, others will be placed on nearby streets next to interstate access ramps. Fliers describing the project will also be posted at welcome centers in East Tennessee.
The contract completion date for the project is June 30, 2005. The contract was awarded to Renfro Construction Company for the amount of $8,253,947.10. The contractor will receive an incentive of up to $5,000 per day up to a maximum amount of $300,000 for completing the project early. If the project is not completed by June 30, 2005, $5,000 per day will be deducted from the contractor’s payment. Those deductions will be unlimited.
Here is the construction plan, step by step. Impacted bridges are listed below.
Beginning March 1, 2004, the contractor will work on the I-75 north/south (I-640 east/west) portion of the project. This work will include milling and paving of the shoulders on I-640 in preparation for traffic shift, grinding conflicting striping and clearing brush.
Later in March, the contractor will reduce I-40 east and westbound traffic to two lanes from Bridge # 2 (I-40 east and west over I-75 north/I-640 east ramp) to Liberty Street bridge over I-40 for a period of five (5) weeks. That work will begin after the Nascar Nextel Cup Series at the Speedway on Monday March 29, at 7:00 p.m. The contractor has agreed to work 24-hour shifts 7 days per week on bridge numbers 2, 3, 5, and 7.
Once this work is completed the contractor will begin work on either bridge number 1, 4 or 6. The contractor will only be allowed to work on one of these bridges at a time until each one is completed. The contract requires work to begin on each bridge on a Friday at 7:00 p.m. and continue in 24-hour shifts, 7 days per week, until completed.
During the summer months twenty-one different interchange ramps in this section will require improvements and repairs. Ramps I-75 south to I- 640 east, S.R. 9 to I-640 east, I-640 west to S.R. 9, I-640 west to I-75 north, I-75 north to S.R. 62 east and I-75 north to S.R. 62 west will be included in a schedule yet to be determined. As much of the ramp work will be done over the weekends as possible. Ramps will not be closed simultaneously with exception of I-75 south to I-640 east and S.R. 9 to I-640 east. All other ramps will remain open during work. Detours will be provided.
