EXECUTIVE SUMMARY
City Council Work Session: April 5, 2016
AGENDA ITEM: Municipal Consent - TH 52/CSAH 42
Interchange, City Project 461
AGENDA SECTION:
Public Hearings
PREPARED BY: Patrick Wrase, PE, Director of Public
Works/City Engineer AGENDA NO. 7.a.
ATTACHMENTS: Project Layout APPROVED BY: ddj
RECOMMENDED ACTION: Motion to continue the public hearing to the April 19th
Rosemount City Council meeting.
BACKGROUND
In April of 2015, the City of Rosemount entered into a Joint Powers Agreement with Dakota County for
the reconstruction of the interchange at TH 52 and CSAH 42. This project is the first phase of a
proposed future system interchange for the TH 52/CSAH 42/TH 55 corridor. The primary purpose of
this interchange reconstruction project is to address safety concerns of the Highway 52/42 interchange,
which include sight distance and geometric issues that have contributed to a crash rate that is above the
statewide average at this interchange. The project includes the expansion of CSAH 42 to a 4-lane highway
through the TH 52 bridges and eastward to Conley Avenue. From Conley Avenue to the east, CSAH 42
will taper back into a two-lane section.
The eastern extent of the project is as of the current date not yet determined. City and County staff will
be refining the eastern terminus over the next week. We are also considering the extension of trunk water
main under the bridge in coordination with the project to potentially save some future cost. The Public
Hearing should be continued to the April 19th Rosemount City Council meeting at which time the eastern
project limit will be determined as well as water main cost estimates.
SUMMARY
Staff recommends the Public Hearing be continued to the April 19th Rosemount City Council meeting at
which time the eastern project limit will be determined as well as water main cost estimates. A Resolution
of Municipal Consent will be considered by the Rosemount City Council at that time.
