New restrictions on the Clark Memorial Bridge could reduce semitruck traffic and push them over to toll bridges.The Kentucky Transportation Cabinet said that soon, reduced weight limits will be posted for vehicles crossing the George Rogers Clark Memorial Bridge.The 95-year-old connector, also known as the Second Street Bridge, is one of two free bridges connecting Louisville to southern Indiana. KYTC said the decision was made after a routine inspection found deterioration. They said the bridge is safe, but these weight changes will better protect the structure from damage and ensure continued safety. The changes, defined by vehicle and axle types, include the following: Type II – 25 tons (previously 27 tons) Type III – 29 tons (previously 34 tons) Type IV – 36 tons (previously 40 tons) 5 Axles – 31 tons (previously 40 tons) 6 Axles – 32 tons (previously 40 tons) 7+ Axles – 34 tons (previously 41 tons) There will be no change for Type I trucks, such as passenger cars, pickups, SUVs, vans, etc.The changes go into effect on Tuesday.Vehicles exceeding the newly-posted weight limits are advised to use alternate routes, like one of two nearby toll bridge: the Abraham Lincoln and John F. Kennedy Memorial Bridges (Interstate 65) in downtown Louisville.The Sherman Minton Bridge (Interstate 64) can be used over in west Louisville.KYTC said the inspection also found further deterioration in the steel supporting the northbound sidewalk so they will be modifying those.Back in March, a semitruck went over the side of the Clark Memorial Bridge, dangling off it for hours. The sidewalk was closed for weeks for repairs.The northbound sidewalk will close Tuesday at 10 a.m. Intermittent lane closures in the northbound lanes will happen between 10 a.m. and 2 p.m. to facilitate the sidewalk closure.
