Interregional Corridor Goals

IRC Goals› Maintain safe, timely,

and efficient transportation service between regional centers.

› Enhance economic vitality of the State.

Interregional Corridor Standards

IRC Performance Standards› 1-Hour average travel

speed 55 mph average for TH

23 60 mph average for I-90

› Limited direct access along the corridor. ½ mile full access

spacing in-town 1 mile full access spacing

in rural areas

Interregional Corridor Improvement Strategies

Reduce number of traffic signals

Consolidate access points

Add passing opportunities

Encourage development of local traffic alternative routes.

As part of the overall CIMS initiative and consistent with the Minnesota GO Vision, MnDOT provided $30 million through a competitive solicitation in 2013 to fund trunk highway projects that improve quality of life, environmental health or economic competitiveness.

N

Improved safety—Studies show a 70 percent reduction in fatalities and a 42 percent reduction in injury crashes where RCIs are used.

A typical four-lane divided highway intersection has 42 possible vehicle conflict points. RCI's reduce conflict points to as few as 18.

Reduced Conflict Intersection (RCI)Increasing safety; decreasing T-Bone (right angle) crashes

Where in Minnesota are RCIs located?•County Rd. 24, Willmar•Hwy 169 and County Rd. 3, Belle Plaine•Hwy 36 and Keats Avenue, Lake Elmo•Hwy 10 and County Rd. 8, Becker•Hwy 169 and 173rd St., Jordan

MnDOT also plans to build additional RCIs in the next five years in Cologne, Cannon Falls, Vermillion, Zumbrota, Cotton, Ham Lake, Ramsey and Oakdale.
