ST. PAUL  (AP) - This year's state road construction projects include work on the Interstate 694 and Highway 10 interchange in the Twin Cities, and final work on an Interstate 35 bridge in Duluth.

The Minnesota Department of Transportation announced its road construction program for 2012 on Thursday. The program includes 316 projects around the state, and will cost $1.1 billion.

Other projects lined up include work on the Highway 52 Lafayette Bridge in St. Paul and resurfacing portions of Highway 10 between Clear Lake and Big Lake. Projects also include improving safety at railroad crossings and fixing runways at regional airports.

MnDOT Commissioner Tom Sorel says this year's program will help the economy by supporting thousands of jobs.
