Split Rock River to Chapins Curve<br />

<strong>State</strong> Project No. 3806-60<br />

http://www.dot.state.mn.us/d1/projects/hwy61_split_rock/index.html<br />

Environmental Document Approval Date: 12/4/2009<br />

Municipal Consent Approval Date: Not Needed<br />

Geometric Layout Approval Date: 09/21/2008<br />

Construction Limits Established Date: 07/02/2008<br />

Original Letting Date: 11/23/2001<br />

Current Letting Date: 02/12/2010<br />

Construction Season: 2010/2011<br />

Estimated Substantial Completion: Fall 2011<br />

Project History:<br />

The Hwy. 61 Rehabilitation Project includes<br />

reconstruction of 3.4 Miles of Hwy. 61 in Lake<br />

County to improve highway safety by correcting<br />

existing design issues such as substandard<br />

horizontal curves, poor sight distance, narrow<br />

shoulders, steep in-slopes, and clear zone<br />

obstructions along the corridor. The<br />

reconstruction of Hwy. 61 will also reduce<br />

maintenance costs by replacing a deteriorating<br />

road core with a new structurally sound road core.<br />

Bicycle/pedestrian accessibility has been<br />

addressed by the addition of a bicycle/pedestrian<br />

underpass that connects the wayside rest just<br />

south of the Split Rock River to the existing<br />

bicycle/pedestrian trail.<br />

Project Benefits:<br />

Improved highway safety, increased sight<br />

distance, reduced maintenance costs, bike/ped<br />

accessibility<br />

Project Risks:<br />

If actual elevation of bed rock varies from the rock<br />

lines used for computation of quantities, the<br />

project costs could change significantly<br />
