ST. CHARLES, Missouri (KSDK) -- Missouri's Blanchette Bridge is getting smaller.
The remaining steel truss on the bridge's westbound lanes was blown up by demolition crews shortly before 11 a.m Tuesday.
More than 4.5 million pounds of steel dropped over a thousand feet into the Missouri River.
A 350-foot section of the Blanchette Bridge was brought down last month.
The Blanchette Bridge blasting is part of a $63 million, year-long project to replace the westbound span.
