Specifications & Plans
SLIDE 18
Using the winning bidders unit cost and the quantities for each project, there is approximately a
$270,000 per mile per lane savings when constructing the overlay versus
replacement.
Cost Saving Update
SLIDE 19
- Segment 4 (Overlay) – 56 lane-miles
- Segment 5 (Overlay) – 28 lane-miles
Construction began July 2017
