ST. CHARLES, MO (KTVI)-- The days are numbered for drivers using the old westbound lanes of the Boone Bridge.
MoDOT broke ground to build a new westbound Daniel Boone Bridge Thursday morning.
The new bridge will replace the three narrow lanes on the original bridge built in 1935.
The $110 million bridge will be built upriver, causing little traffic impact.
The bridge will have wider lanes and a special path for pedestrians.
MoDOT expects traffic to be on the new bridge by late 2014 and then will take down the old bridge in 2015.
