The Minnesota Department of Transportation on Friday announced that it had rejected all of the bids received for the expansion of Highway 14 west of North Mankato. The lowest bid reportedly came in at more than 30% above Mn/DOT’s estimates, or $6 million over the project’s $18 million cost. Officials say they will now be looking at alternative construction methods and will announce the new plans in 2 weeks. The first phase of expanding Highway 14 to 4 lanes from North Mankato to New Ulm involves a stretch from North Mankato to Nicollet County Road 6, as well as a new interchange at County Road 41. Mn/DOT officials say that the department is committed to finishing the project on the same timeline, which calls for it’s completion in 2013.
