Close to 2 years ago, I made a
post about underway and upcoming interchange projects in Minnesota. Here's an update, with several completed projects from that list and some new interchange (and roundabout) projects in the pipeline.
Completed (includes new roundabouts):US 10/Otter Tail CSAH 34 near Perham
US 10/Ramsey CSAH 96 - Partial interchange
MN 13/Old MN 101 in Savage
US 14/Nicollet CSAH 41 near Mankato
US 14/Blue Earth CSAH 12 near Mankato
US 14/Waseca to Owatonna
MN 15/Stearns CR 120 in St. Cloud (Minnesota's 2nd DDI)
MN 23/Paynesville Bypass
MN 36/English St in Maplewood
US 52/Dakota CSAH 47 in Hampton
US 52/Elk Run near Oronoco (Minnesota's 1st DDI)
US 52/65th St NW in Rochester (not listed previously, a folded-diamond interchange built in 2013)
US 59/MN 60 in Worthington - New roundabouts
US 61/Washington CSAH 4 in Hugo - New roundabout
US 63/Olmsted CSAH 14 near Rochester - New roundabout
I-94/Albertville
US 169/Hennepin CSAH 30 in Osseo/Brooklyn Park (was moved from 2014 to 2013)
US 169/I-494 in Bloomington
US 169/Blue Earth - 3 new roundabouts
US 212/MN 284 in Cologne - A "Reduced Conflict Intersection". Effectively a 3/4 intersection with U-turns on either side. It's very similar to the intersection improvements Maryland has done on US 15 north of Frederick and US 301 on the Eastern Shore, or the "Superstreet" concept of NCDOT.
MN 284/10th St in Waconia - New roundabout
I-494/34th Ave in Bloomington (not listed previously, converted interchange to a DDI)
I-694/US 10/MN 51
Under construction:MN 7/Louisiana Ave in St. Louis Park
US 10/Benton CSAH 2 in Rice
MN 13/Dakota CSAH 5 in Burnsville
I-35E/Cayuga St in St. Paul (part of the Cayuga Bridge project, replaces 3/4 interchange at Pennsylvania Ave)
MN 36/Hilton Trl in Pine Springs
MN 36/Stillwater Bridge (includes MN 95 interchange)
US 52/Goodhue CSAH 24 in Cannon Falls
I-94/US 52 (part of the Lafayette Bridge project)
US 169/Scott CSAH 69 in Shakopee
I-394/Ridgedale Dr in Minnetonka - Adding a WB on-ramp to complete a full interchange.
New/upcoming projects (includes known roundabout projects):US 10/US 169/Anoka CSAH 83 in Ramsey - A partial-folded diamond (EB on-ramp loop) is planned. If the county can get bond funding, they hope to start the project this year.
US 14/MN 111/CSAH 23 near Nicollet - Part of the Nicollet bypass (to be built 2015-16). MnDOT considered downsizing the junction last fall based on
preliminary findings, but an interchange with roundabouts is
currently planned.
US 14/Steele CSAH 43 near Owatonna - Phase 1 (near Owatonna) of the plan to bridge the 4-lane gap between Owatonna and Dodge Center was funded as part of the Governor's "Corridors of Commerce", with construction to begin this year. A diamond interchange was the original plan at CSAH 43 (from the EIS vision for a freeway facility). This was then changed to a Reduced Conflict Intersection, but is now going to be built as a standard at-grade intersection instead.
US 14/MN 42 near Eyota - Mentioned upthread, a roundabout will be built in 2015.
MN 15/33rd St in St. Cloud - This is on the existing freeway segment of MN 15 south of MN 23. The plan is for a diamond interchange with roundabouts to be built this year.
MN 22 at both Blue Earth CSAH 17/Madison Ave and Adams St in Mankato - Roundabouts at both intersections are planned for this year.
MN 29/Douglas CSAH 28 near Alexandria - A roundabout is planned here as part of a larger project that will also reconstruct the I-94/MN 29 interchange (more or less as-is) and widen MN 29 to 4 lanes south to the new roundabout. The physical location of the roundabout will be at CR 87...CSAH 28 will be realigned to meet MN 29 at the new location.
MN 29/MN 55 near Glenwood - Not currently funded, the plan is to replace the existing at-grade intersection with a bridge on MN 29 over both MN 55 and the adjacent Canadian Pacific tracks. The connection between the two routes would be made via an improved 160th St.
I-35W/4th St in Minneapolis - Previously expected in 2012, construction will begin this year on a new on-ramp from 4th St to northbound I-35W near downtown Minneapolis.
US 52/Dakota CSAH 66 near Vermillion - MnDOT plans to build a "Reduced Conflict Intersection" this year.
US 52/Dakota CSAH 86 near Cannon Falls - Originally planned as a Reduced Conflict Intersection in 2013, a folded-diamond interchange will now be built in 2015.
US 52/Goodhue CSAH 9 south of Cannon Falls - This "pop-up" project (as Monte calls it) will build a folded-diamond interchange this year.
US 59/Willow St in Detroit Lanes - A roundabout is planned for this year.
MN 60/US 71 North in Windom - A roundabout is planned for 2017.
US 61/MN 97 in Forest Lake - This new 2015/16 project will build roundabouts at each of the 61/97 junctions. According to current plans, "free rights" will be provided for each MN 97 through-right movement off 61, and also from WB 97 to NB 61.
I-94/US 75 in Moorhead - Planned for 2016, there are 3 alternatives being considered for reconstruction of this interchange: a DDI, a 5-ramp par-clo, and a 6-ramp par-clo.
MN 100/St Louis Park - The long-awaited full reconstruction of MN 100 in St. Louis Park begins this year. The plan includes reconstructing the interchanges at MN 7 (into a 5-ramp par-clo) and CSAH 5/Minnetonka Blvd (into a tight diamond).
MN 101/Hennepin CSAH 144 in Rogers - Planned for this year, this project will effectively complete a freeway on northbound MN 101 between Rogers and Elk River (signals will remain for southbound MN 101 near I-94). The plan is for a diverging diamond.
MN 610/Maple Grove - As noted upthread, construction begins this year to extend MN 610 to I-94.
