Project Description

SP 3001-29: MN 47 & CSAH 5 ROUNDABOUT AND MN 47 AND CSAH 8 ROUNDABOUT

Brief Description: State Project (SP) 3001-29 includes construction of a single lane roundabout at the intersection of Trunk Highway (TH) 47 at County State Aid Highway (CSAH) 8 and TH 47 at CSAH 5 in Isanti County. This contract will provide MnDOT Final Construction Limits developed in Bentley OpenRoads Designer CE Standards to support Right of Way (ROW) acquisition and the National Environmental Policy Act (NEPA) process, an approved environmental Categorical Exclusion (CATEX) document and Wetland Permit Exhibits for permitting activities completed by the State. The goal of this contract is the development of a biddable final plan-set and special provisions for SP 3001-29 on TH 47 to be delivered on schedule and within budget including all Municipal, State, and Federal approvals, preparation for State acquired ROW acquisition, permitting, and project utility relocations.

Exhibit A: Specifications, Duties, and Scope of Work

PROJECT LOCATION:

The Trunk Highway (TH) 47 & County State Aid Highway (CSAH) 5 intersection is in a rural area of Isanti County with rural

homes and neighborhoods nearby. TH 47 is a two-lane, two-way, conventional, 60 mph, minor arterial at the location

of CSAH 5. CSAH 5 east and west of the intersection has an unposted speed (55 mph) and is classified as a major

collector. CSAH 5 is a well-known local connection between Princeton and Isanti paralleling the busier CSAH 8 (4 miles

south) and has lower volumes than TH 47 (AADT): north and south 4,077; east 2,695; west 1,300).

The TH 47 & CSAH 8 intersection is in a rural area of Isanti County with rural homes, neighborhoods, and businesses

nearby. TH 47 is a two-lane, two-way, conventional, 60 mph, minor arterial at the location of CSAH 8. CSAH 8 east of

the intersection has an unposted speed limit and is classified as a major collector; west of the intersection, CSAH 8 has

an unposted speed limit and is classified as a minor arterial. CSAH 8 is a well-known connection locally and regionally

between Zimmerman and Isanti and has relatively similar volumes to TH 47 AADT: north 4,077; south 9,572; east 3,125;

west 5,145).

STATE PROJECT (SP) 3001-29 OVERVIEW:

The proposed safety improvement studied to address the safety needs identified at these intersections is constructing

a single-lane roundabout. A roundabout is expected to significantly reduce the frequency and severity of crashes by

controlling vehicle speeds, eliminating the potential for right-angle and head-on collisions, and improving overall

intersection operations. This solution aligns with proven safety strategies and offers a long-term remedy to the ongoing

crash history. The project has received both State and Local Health Safety Improvement Program (HSIP) funding for

2029.

The roundabout is anticipated to be constructed under detour. Portions of TH 47 at CSAH 5 were mucked in 2003 with

project SP 0206-49 (TH 47). There is a BUMP sign on TH 47 approximately 500 feet south of CSAH 5. Work with the

District Materials Engineer on soil corrections to be incorporated into the plan. Poor materials and additional mucking

are anticipated near the bump signs and in the widening areas.

The following project assumptions were pulled from the project scoping report:

I. Consider additional county opportunities identified during predesign.

II. It is anticipated that unsuitable materials will be encountered on this project and soil corrections will be

needed.

III. 100-year floodplain adjacent to CSAH 5 intersection and approximately 780 feet east of TH 47 along CSAH

8.

IV. Remove lighting at existing intersections. Install approximately 14 lights at each roundabout.

V. Remove existing Rural Intersection Warning System (RICWS)/flashing beacon systems at both intersections.

VI. Bike and pedestrian rural shoulder accommodations.

VII. Consider shoulder rumbles on approaches to splitter island.

SP 3001-29 SCOPE OF WORK OVERVIEW:
