Project Description: |
|
|
This project, located near Bowling
Green, Kentucky, involved the widening
of Interstate 65 from 4 to 6 lanes, with consideration of a future 8 lane
roadway. JD&Q's section of the
project involved five (5) bridges, including the widening and replacement of the KY 101 bridge over I-65, which is
located at a diamond interchange
with ramps at all four quadrants.
After considering several alternatives, it was decided to replace the
existing bridge in order to provide a
9.0m (30 ft) clear zone along the outside shoulders of the 6-lane
Interstate roadway, improving safety and avoiding the need for
guardrail. The existing 2-lane bridge
was also widened from 14.55m (47.7 ft) to 19.00m (62.3 ft) to add a center turn lane, and utilized staged construction to maintain traffic
in both directions on KY 101. The new
bridge is 77.77m (255.2 ft) long,
including 4-spans with lengths of 12.1-29.0-29.0-12.1 meters
(39.7-95.1-95.1-39.7 feet), and is framed using spread 840x1220mm (33"x48") PPC Box beams with a composite
concrete deck. The box beams were
used to minimize the structure depth to provide the required vertical clearance over the widened
Interstate roadway underneath.
The substructures consist of semi-integral
end bents (modified existing end bents) on steel H-piles and multi-column piers with spread footings founded on rock. Estimated construction cost is $820,000 ($51/sf). Construction is scheduled for 2002. |
