Ground was broken Thursday on the new Daniel Boone Bridge just west of Chesterfield.
The $111 million project will replace a 75-year-old span over the Missouri River and link St. Louis and St. Charles Counties.
MoDOT District Engineer Ed Hassinger says the bridge is the final project to make I-64 a true, interstate-quality, highway.
“We’re thrilled today to start on the project,” Hassinger says. “The design is about 90 percent complete and you’re going to see people starting work on the ground this month. The plan is that we’ll have the new bridge open in 2014.”
