I-90 westbound lane closure begins April 19 from Hwy 42 to Hwy 52 for cable median barrier installation

ROCHESTER, Minn. — Westbound Interstate 90 motorists from Hwy 42 to Hwy 52 will encounter a left lane closure in the westbound lanes beginning April 19 as crews begin installing high-tension cable median barrier, according to the Minnesota Department of Transportation.

The lane closure in Olmsted County will be approximately 5.8 miles in length. Mattison Contractors is the prime contractor on the $862,640 project. Work is scheduled to be completed by the end of May.

The barriers are made of three or four steel cables strung on posts. When a car hits the barrier, the posts break and the cables flex, absorbing much of a crash’s kinetic energy. This redirects the vehicle along the median, preventing a cross-median crash.

MnDOT has evaluated the performance of cable median barriers and determined that nearly all of the fatal and serious injury cross median crashes have been eliminated where the barrier has been installed.  There are restrictions on where cable median barrier can be installed but MnDOT is moving forward with strategic installations in locations where the risk of cross median crashes are the highest. To learn more, visit MnDOT’s website about cable median barriers.

Safety

Motorists may encounter lane closures or lane shifts, uneven road surfaces, equipment and other unexpected obstacles when driving near or through work zones. MnDOT advises motorists to: 

  • Find up-to-date information about traffic and road conditions at 511mn.org or get the free smartphone app at Google Play or the App Store
  • Expect delays, especially during peak travel times
  • Go hands-free and minimize other distractions (e.g., don’t eat or drink while driving)
  • Follow posted speed limits; the fine for speeding in a work zone is $300
  • Avoid making lane changes within work zones
