Environmental Document Approval Date: 10/11/2010
Municipal Consent Approval Date: Not Needed
Geometric Layout Approval Date: Pending Approval
Construction Limits Established Date: Assume no R/W need

Construction Season: Spring 2011
Estimated Substantial Completion: Fall 2011
Project History:
This section of Interstate 35 carries an average of
15,900 vehicles per day, approximately 7% of
which are classified as heavy commercial
vehicles. Pavement modeling (based on current
ride quality conditions, existing pavement type,
and traffic levels) indicates this section of road will
need pavement preservation to improve its ride
quality and thereby extend its useful life.
Project Benefits:
Improved ride quality for road users, extend useful
life
Project Risks:
Cross slope correction quantities are not
determined until 90% design stage and could
increase final concrete quantity estimates

PROJECT SUMMARY
I 35
North of Sturgeon Lake to south of Mahtowa
State Project No. 0980-138
Project Description:
Project begins 1.8 Miles south of the north
Pine County Line and continues north to 2.6
Miles south of Carlton County Road 4. All
13.2 Miles of southbound lanes will be
preserved with an unbonded concrete
overlay. 4.5 Miles of the north lanes will be
preserved with an unbonded concrete
overlay. Traffic will be reduced to two-lanes
during construction. Access to Barnum and
Highway 73 at Moose Lake will be provided
during construction.

Construction cost estimates are adjusted to the mid-year of construction, using inflation rates provided by
OCPPM.
The scope changes of the projects led to the delay in Letting and considerable reduction in
costs from the original estimate.
