Subject:Guest Speaker: Zach Johnson, City Engineer
Zach Johnson, City Engineer, will present an update on the I-35/County Road 50 interchange
improvement project - the City of Lakeville’s top transportation priority. The project is critical
to improving safety, replacing deteriorating bridges, and providing needed capacity
improvements along I-35 and brings wide-ranging community and economic benefits. More
than $22 million of local investment has already been made over the last 20 years to prepare
for this improvement.
Lakeville is partnering with Dakota County and MnDOT to coordinate interchange
improvements to increase efficiencies and reduce impacts to the traveling public and existing
businesses.
The project includes:
•Replacing two existing two-lane I-35 bridges with two new three-lane I-35 bridges, new
freeway ramps and new northbound auxiliary lane
•Diverging diamond interchange design
•New additional westbound lane on County Road 5/50 under the I-35 bridges
•Increased vertical clearance under I-35 bridges
•Improved bicycle/pedestrian facilities
The estimated construction cost is $62.5 million. Construction is anticipated to take place in
2028/2029.
