PROJECT SUMMARY
Hwy. 14
Bridge over the Minnesota River in New Ulm (Minnesota River Bridge)
Environmental Document Approval Date: Need Unknown
Municipal Consent Approval Date: Need Unknown
Geometric Layout Approval Date: Need Unknown
Construction Limits Established Date: Need Unknown
Original Letting Date: 1/1/2018
Current Letting Date: 1/1/2018
Construction Season: 2018-2019
Estimated Substantial Completion: 2019
Project History:
Bridge 9200 was constructed in 1963. The most
recent rehab work was done in 2008, fixing the
substructure. Currently the bridge is structurally
deficient and has a sufficiency rating of 38. The
bridge geometrics and safety features are
substandard. The purpose of this project is to
replace a structurally deficient bridge, while at the
same time improving capacity by expanding the
river crossing to four lanes.
Project Benefits:
Removes a structurally deficient bridge from the
state trunk highway system, expands river
crossing to four lanes of traffic (first step of the
larger Hwy 14 expansion project between New Ulm
and North Mankato), provides for a safer
pedestrian crossing over the river at this location,
creates better ramp geometrics at the Front St.
interchange
Project Risks:
Major geotechnical issues with the soils for the
east approach. Anticipate that large quantities of
muck will be present. Currently, the east approach
overtops near the Hwy 14/Hwy 15 intersection.
May need acceleration/deceleration lanes on
bridge for the Front St. interchange. Wetland and
floodplain impacts. Water quality needs to be
addressed. Trail access through Front St.
interchange and across the four-lane highway.
Possibility of flooding during construction. City of
New Ulm will be interested in aesthetic treatments
for the bridge.
