Minnesota is once again going to bat for federal money to fix the Hwy. 169-Interstate 494 interchange -- this time proposing to rebuild it as a national pilot project showing how to economize on design based on local needs.
The interchange now has three traffic signals that cause traffic backups six hours a day on what is otherwise a freeway through Edina, Bloomington and Eden Prairie. In a bid to start work on a new interchange in 2010, the Minnesota Department of Transportation has applied for $135 million from a $1.5 billion pool of federal stimulus money targeted for transportation projects.
If the state wins the $135 million, it would build a new interchange with just six of the eight high-cost, road-to-road fly-over ramps that federal policy normally requires at such a large interchange. MnDOT wants to eliminate two ramps -- the one from east 494 to north 169 and the one from south 169 to west 494 -- to save $30 million. Traffic forecasts show relatively few vehicles would use those ramps because most motorists in that area travel in those directions more conveniently by using the nearby Hwy. 212.
But as a critical condition of receiving the grant, MnDOT also would promise to monitor the performance of the new interchange and build the two ramps later if they turned out to be needed. The point of the pilot demonstration would be to establish what safety and traffic performance measures should trigger adding the ramps.
Although nationwide competition for the money will be fierce, with as many as 5,000 applications, MnDOT is optimistic that the pilot project "is a good selling point," said Khani Sahebjam, MnDOT's deputy commissioner and chief engineer. Award of the money from the Transportation Investment Generating Economic Recovery (TIGER) Fund will be announced later this year or early in 2010.
If the Federal Highway Administration goes for that approach, it would be a turnaround from six months ago. In April, Derrell Turner, administrator of the Minnesota division of the Federal Highway Administration, said absolutely not when MnDOT proposed to drop the two ramps. Turner said then that federal policy requires full, freeway-to-freeway interchanges in a design that remains consistent across the nation.
To the chagrin of the three suburbs flanking the interchange, the federal-state standoff meant the project was not ready to go and could not qualify for any of the $500 million in federal economic recovery funds MnDOT got earlier this year to create jobs.
Since then, upper-level discussions between state and federal highway officials in Washington, D.C., along with support from other states interested in similar design variations, have encouraged MnDOT to propose the project as a pilot in "performance" design, Sahebjam said.
