LOUISVILLE, Ky. (WDRB) -- Crews with Walsh Construction continue to make progress on the deck of the John F. Kennedy Memorial Bridge.

According to a news release, a new floor system is being installed, which is expected to add decades of new life to the 52-year old bridge.

Most of the west side of the old deck has been removed, with old steel removed and new steel being installed. The new floor system is being built on top of existing floor beams, with all new stringers, bearings and diaphragms the length of the Kennedy Bridge. More than 3.5 million pounds of steel are being replaced.

Stringers are the primary vertical support members of the floor system, running with traffic. After the new stringers are installed, a new concrete deck will be formed. The new deck will include 5,700 cubic yards of concrete and 2.6 million pounds of reinforcing steel.

The deck of the Kennedy is 250,000 square feet. Crews with Walsh Construction are saw cutting the deck into approximately 3,000 slabs. Each slab weighs around 8,000-9,000 pounds.

The work is being performed in two phases. Phase one focuses on the west side of the Kennedy Bridge and is expected to be complete in July. During phase two, the same work will be repeated on the east side of the Kennedy. Phase two is expected to run July-October.

A new approach on I-65 South (Indiana approach) is also being built. The work includes complete removal of the existing approach. The new approach includes 4.1 million pounds of new steel beams and 2,100 cubic yards of new concrete.
