New weight limit signs placed this morning
PADUCAH, Ky. (Nov. 22, 2019) -- The Kentucky Transportation Cabinet has restored normal weight limits on U.S. 60 Cumberland River Bridge at Smithland in Livingston County. Weight limits on the bridge had been reduced since late July when inspectors found several beams beneath the bridge deck had been damaged by overweight trucks crossing the structure.
On Monday, a contractor completed a two-week repair project aimed at restoring normal weight limits. Bridge engineers completed an inspection of the repairs and ran calculations confirming the bridge could return to normal weight limits.
The new weight limit signs were posted Friday morning. In a posting memo, Load Rating Engineer Dora Alexander with the KYTC Division of Maintenance noted that the bridge preservation staff had determined the repairs had allowed the posting of new load limits as follows:
- Type 1: 27 tons--Two axle single unit trucks
- Type 2: 29 tons--Three axle single unit trucks
- Type 3: 34 tons--Four axle single unit trucks
- Type 4: 43 tons--Five axle SEMI trucks
- Single Unit Vehicle--5 axles: 34 tons
- Single Unit Vehicle--6 axles: 34 tons
- Single Unit Vehicle--7+ axles: 35 tons
Several of the truck categories gained 6 to 12 tons per load from the more restrictive limits that have been in place since July.
KYTC engineers have worked with law enforcement agencies to provide more diligent monitoring of truck traffic crossing the bridge. That effort to keep grossly overweight trucks off the bridge will continue.
Truck drivers are responsible for obeying posted load limits on all bridges.
The U.S. 60 Cumberland River Bridge at Smithland, also known as the Lucy Jefferson Lewis Memorial Bridge and the Smithland Bridge, is at U.S. 60 Livingston County mile point 12.697. The 1,817-foot through truss structure was opened to traffic in 1931. The U.S. 60 Cumberland River Bridge at Smithland is at Cumberland River navigation mile point 2.7.
The Kentucky Transportation Cabinet is in final design phase for construction of a new bridge immediately downstream from the existing structure. The new, $45 million bridge remains on track for bidding in February 2020 with construction expected to take just over two years to complete.
