JEFFERSON CITY, Mo. (AP) Visitors to the Missouri Capitol will have to weave their way through a construction zone as the 100-year-old building undergoes a major renovation.

Crews were erecting metal fences March 2 and dumping gravel on the Capitol lawn to serve as a staging area for heavy construction equipment during the project that will last until late 2020.

Workers will be erecting scaffolding around the building to repair cracked and crumbling stone on the exterior of the Capitol, from ground level to the top of the dome.

Chicago-based Bulley & Andrews Masonry Restoration has been awarded the $28.7 million contract.

An estimated 450,000 people visit the Capitol annually. It will remain open, though the south roadway will be closed and parking will be limited.
