Typically, cars, mini-vans and pickup trucks are under the 16-ton weight limit.
Based upon a recent inspection of the bridge, INDOT has determined that vehicles weighing 16-tons are not allowed to travel on this bridge.
The conditions of the bridge have warranted placing this weight restriction on this bridge.
INDOT Media Relations Director for the Crawfordsville District Debbie Calder said the weight restrictions had nothing to do with recent repairs to the bridge.
"Last year, the bridge was closed due to a crack in one of the gusset plates, now additional repairs need to be made to address the deteriorated gusset plates," she said.
Signs displaying "Weight Limit 16 Tons" are posted on both sides of the bridge and at the intersections of SR 59 and SR 46, SR 246 and SR 46, plus in Spencer at US 231 and SR 46.
The through truss bridge was originally built in 1933.
A repair contract is being developed and as soon as a timeline is known for construction it will be released.
INDOT reminds motorist to use caution and consider worker safety when traveling through a work zone.
