During afternoon rush hour, traffic jams are a common sight at the Fish Lake Interchange in Maple Grove, where Interstates 94 and 494 converge.
The problem: I-94 drops from four lanes to three as it splits off to the northwest, and drivers traveling from northbound I-494 and westbound I-94 are forced to merge into a center lane.
"It's a known bottleneck," said John Hagen, transportation operations engineer for the northwest metro suburb.
More than 100,000 vehicles pass each day through the interchange, which was identified in a 2020 Minnesota Department of Transportation (MnDOT) and Metropolitan Council Freeway System Interchange study as one of 17 in the metro area needing upgrades to improve safety and traffic flow.
Maple Grove has applied for a $4.9 million Corridors of Commerce grant from MnDOT to build a fourth travel lane from the busy interchange to Weaver Lake Road. The lane, to be added on the west side of I-94, would reduce congestion by eliminating the need to merge into the center lane and spreading out traffic.
"We are proposing a low-cost, high-benefit project," Hagen said.
The city of Rogers has applied for an $8.5 million Corridors of Commerce grant to add an auxiliary lane on westbound I-94 to handle traffic getting on and off the freeway. The lane would run from Hemlock Lane to Weaver Lake Road.
A third application, submitted by the I-94 West Corridor Coalition, seeks $13.4 million to cover the cost of adding both the extra travel lane and the auxiliary lane.
