TH 3 ROADWAY IMPROVEMENTS
ROSEMOUNT, MINNESOTA
CITY PROJECT NO. 239
EXECUTIVE SUMMARY
This report addresses the feasibility and cost for the construction of left and right turn
lane treatments on TH 3 from 143rd Street to north of Connemara Trail. These
improvements are recommended in order to promote the safe and efficient access to the
Armory/Community Center from TH 3. Mn/DOT has required that at a minimum a by
pass lane be pursued as part of the access permit approval. The by pass lane would be
100% City cost.
We recommended Alternative A which includes the construction of a continuous left
turn lane, from 142nd Street through Connemara Trail and right turn lanes at major
intersections and driveways. This Alternative provides the most efficient and safe
improvement for the project area. The estimated project cost would be approximately
$309,000. The funding for the project would be through a cooperative agreement
between the City of Rosemount and the Minnesota Department of Transportation
(Mn/DOT)
The project would be constructed and completed prior to the opening of the
Armory/Community Center. Based on the existing and projected average daily traffic
(ADT) and the existing and proposed accesses on TH 3, this project is feasible.

I. INTRODUCTION
1.1 Authorization - The City Engineer requested Orr-Schelen-Mayeron &
Associates (OSM) to prepare an engineering feasibility report for
improvements required on TH 3 associated with the proposed
Armory/Community Center access.
30 MPH - 145th to 143rd Street
40 MPH - 143rd Street to Armory Site
50 MPH - Armory Site to 132nd Street
OSM Project No. 4845.20 Page 2
1.2 Data Available - Information and materials used in the preparation of this
report include:
• City of Rosemount Aerial Photos/Topography Maps
• Armory/Community Center Site Plan
• City of Rosemount and Mn/DOT ADT Volumes
• Mn/DOT State -aid Standards
• Mn/DOT Roadway Design Standards
1.3 Project Background = This project would be constructed in conjunction
with the proposed Armory/Community Center project. The Armory site is
located on TH 3 between 142nd Street and Dodd Road. Two site accesses
will be provided from TH 3. Access will also be provided to the Armory
via Dodd Road. The TH 3 Roadway Improvement Project would include
left and right turn lane treatments from 143rd Street to north of Conemara
Trail.
It is the intent of the project, by providing the left and right turn
channelization, to maintain a high level of service and safety to the existing
and proposed businesses and residences on TH 3.
1.4 Traffic - Existing ADT volumes on TH 3 were collected from the City of
Rosemount and Mn/DOT. The existing ADT volume in the project area
is 8,700 vehicles per day.
The 20 year projected ADT is estimated at 18,270 vehicles per day. This
ADT is based on the Mn/DOT State Aid projection factor of 2.1 over a
twenty year period for the Dakota County area.
The existing speed limit is variable through this length of TH 3. The
®
speed limits and approximate locations are shown below:
30 MPH - 145th to 143rd Street
40 MPH - 143rd Street to Armory Site
50 MPH - Armory Site to 132nd Street
OSM Project No. 4845.20 Page 2
For the purpose of this analysis, it was assumed that the PM peak hour
P � Y �
volume was 10% of the ADT and that the directional split was 50/50.
Based on Mn/DOT Roadway Design Standards, a facility with a speed of
40 MPH, a peak hour volume 435 VPH in each direction, and as few as 40
vehicles turning left, left turn lane treatments should be provided as a
minimum. This represents the worst case condition. The proposed
development site will exceed the 40 vehicles per hour requirement.

2. PROPOSED IMPROVEMENTS
2.1 Alternatives - Two roadway improvements rovements alternatives have been
developed based on coordination with the City and Mn/DOT. Each
alternative is discussed below and are illustrated on maps in the Appendix.
Figure 2, located in The Appendix, shows the typical roadway section for
the existing condition and each alternative.
Alternative - A continuous center left turn lane providing for left turning
vehicles into all entrances and driveways. Right turn lanes are included at
major intersections.
Alternative B - A bypass lane providing for through traffic to pass (on the
right) left turning traffic. Right turn lanes are included at major
intersections. This alternative is the minimum requirement of Mn/DOT.
2.2 Right of Way/Access - The project is planned to be constructed in the
existing MN/DOT right-of-way. Currently the right-of-way varies from 90
feet near 143rd Street to 150 feet adjacent to the Armory site. No
temporary construction easements are anticipated to be needed along the
project.

3. FINANCING
3.1 Cost Estimate - The cost estimates are based on 1991 and 1992
construction costs and include a 10% contingency factor and related
administrative costs. The administrative costs are estimated at 30 percent
and include legal, engineering, interest and other administration. Detailed
cost estimates can be found in the Appendix.
The following is a summary of the estimated projects cost for each
alternative described previously.
Alternative A - $309,000.00
Alternative B - 91,000.00
3.2 Funding - Funding for Alternative B would be the responsibility of the
City as part of the Armory/Community Center project. Alternative A
would be funded through a cooperative agreement with Mn/DOT for the
majority of the difference between Alternative A and Alternative B.
It is anticipated that Mn/DOT would fund 100% of the actual construction
cost difference plus 8% for engineering or approximately $190,000 through
the cooperative agreement process.
OSM Project No. 4845.20 Page 5
4. RECOMMENDATIONS
It is our recommendation that Alternative A, a continuous center left turn lane be
constructed, based on the existing and projected ADT volumes and the existing
and proposed accesses on TH 3.
The project would provide for the most efficient and safe movement of traffic on
TH 3 now and in the future.
The funding for the project would be through a cooperative agreement between
the City and Mn/DOT. This cooperative agreement would provide the City and
Mn/DOT with a much safer and efficient project for very little additional cost.
The Cooperative Agreement funds need to be secured from Mn/DOT upon
approval by the City Council to proceed on Alternative A. The Coo erp ative
Agreement requires that a letter reguesligg these funds along with a resolution
from the City Council be sent to Mn/DOT to initiate the approval of these funds
Mn/DOT has indicated a willingness to enter into a Cooperative Agreement
process.
