DANE/ROCK CO: Info on I-39/90 expansion and related projects.

What’s going on this week,  per the DOT:

WIS 73 reconstruction 

Interstate 39/90 north to US 12/18 near Cambridge and Deerfield

  • WIS 73 is CLOSED to through traffic until November 2014.  WIS 73 remains open for local traffic.
    • Access to area businesses along WIS 73 to remain open.
    • Alternate routes required for through travelers.
    • Signed detour route: I-39/90 and US 12/18.
  • Northern section of WIS 73 (just north of County B to south of US 12/18).
    • Excavation and grading operations are almost complete on this section.
    • Permanent roadway stone is in place from 1,600 feet south of Koshkonong Road to just north of County PQ, which will improve mobility in the area.
    • Local traffic can still drive through this area. Delays are anticipated, especially between County PQ and Fadness Road.
    • Note: WIS 73 will be paved in fall 2014.
  • Middle section of WIS 73 (north of County B to just south of County A).
    • Asphalt removal in this area will start next week.
    • Please drive with caution and be alert for crews working in this area.
  • Storm sewer placement is underway, which improves drainage in some areas. The second half of the box culvert replacement will start next week; the single lane will move from the east side to the west side of the roadway (over new box culvert).
    • Note: The travel lane near box culvert work (about 1,500 feet north of County B) is narrow. Most vehicles and delivery trucks should be able to safely pass; however, large farm vehicles with implements may not be able to safely navigate this section of roadway.
  • The WIS 73 and WIS 106 intersection, just north of I-39/90, remains open to traffic until reconstruction in late summer 2014.
