Construction of Highway 63 from intersection with Minnesota 16 west of Spring Valley to Stewartville is among the more than 300 construction projects scheduled for 2014.

Construction of the $4.95 million project will begin May 1 and run through Sept. 1. Motorists can expect four to six weeks of a detour followed by daily lane closures with flaggers, according to the Minnesota Department of Transportation. Rochester Sand and Gravel is the contractor.

About 11 miles of Highway 63 from the junction with Minnesota 16 to the south end of the Root River bridge in Stewartville is slated for pavement resurfacing and rehabilitation. The portion from Mower County Road 2 north of Deer Creek to Mower County 1 near Racine will have mill and overlay.

Another project is preservation and maintenance of bridges over Deer Creek and Bear Creek during the same timeframe. The $250,000 project will also have a detour.

Another area project includes Highway 16 in Fillmore County when two bridges near Lanesboro are replaced June 3 through Aug. 29. The $945,660 project will cause a detour. Minowa Construction is the contractor.

Also, Highway 52 from the Iowa state line to north of Fillmore County Road 22, a distance of about 10 miles, will have pavement resurfacing and rehabilitation. The construction will result in daily lane closures with flaggers. The $3.27 million project will run from May 5 to June 30. Mathy Construction is the contractor.

These projects will do much to improve highways, bridges and other state transportation infrastructure to ensure the safety and mobility of the travelling public, according to the Minnesota Department of Transportation.

The $1.1 billion 2014 construction program of 308 projects includes work on 74 projects in the Twin Cities and 194 projects in Greater Minnesota. An additional 40 projects statewide will improve safety at railroad crossings, and make improvements on runways and terminals at regional airports. The work includes projects funded by the Corridors of Commerce program, a bonding effort aimed at improving roadways for freight travel.

"This program will provide vital upgrades to our transportation system," said MnDOT Commissioner Charlie Zelle. "The Corridors of Commerce projects will ensure that roadways vital to business use will get needed improvements."

Because of the number of work zones motorists will encounter as crews perform road construction and maintenance work, MnDOT asks drivers to be alert on the road this summer.

MnDOT urges motorists to:

•Check www.511mn.org for up-to-date information about traffic and road conditions.

•Minimize distractions (e.g., don't use cell phones or eat or drink while driving)

•Follow posted speed limits; fines double in work zones.

•Expect delays, especially during peak travel times.
