Long-term Hwy 12, I-394, I-494 ramps closing in west metro
MnDOT will close multiple ramps on Highway 12 and interstates 394 and 494 beginning June 10, disrupting west-metro travel as crews rebuild and resurface the roadway.[1]
The ramp from westbound I-394 to northbound I-494 will close June 10 and remain shut through June 14.[1] Beginning June 15, the ramp from westbound Highway 12 to southbound I-494 will close through early July.[1] Also beginning June 15, the ramps from northbound I-494 to westbound Highway 12 and from westbound Highway 12 to Carlson Parkway will close through late July.[1]
MnDOT began a pavement preservation project on Highway 12 between Shoreline Drive in Wayzata and I-494 in Minnetonka on April 20.[1] The three-mile, $50.9 million project includes full reconstruction of sections built in 1970, resurfacing, drainage repairs, lighting replacement, accessibility upgrades and repairs to up to 20 ramps. Two full weekend closures of Highway 12 took place May 1-4 and May 8-11 to allow early drainage and resurfacing work. MnDOT says the work will extend the roadway's life by more than 20 years and that some ramp closures will stretch into November 2026.[1]
The mainstream summary emphasizes the upcoming ramp closures but does not address the broader context of the aging infrastructure that necessitates such extensive repairs. According to MnDOT and analyses, much of Minnesota's highway system was built between the 1950s and 1960s, with a typical lifespan of 40 to 70 years, meaning that many roads, including the section of Highway 12 being rebuilt, are now reaching the end of their functional life. This deterioration is exacerbated by environmental factors and heavy traffic, leading to urgent reconstruction needs that the summary fails to highlight.[2]
Additionally, while the summary mentions the $50.9 million project budget, it overlooks the chronic underinvestment in highway preservation that has led to a significant maintenance backlog. A University of Minnesota study indicates that Minnesota faces a $17.7 billion deficit for state roads over the next two decades, largely due to a shift from federal to state funding and rising construction costs. This context suggests that the ramp closures are not just isolated incidents but part of a larger pattern of deferred maintenance and funding challenges facing the state's infrastructure.[2]
