Hwy 169

St. Peter, Le Sueur

About this project

Construct a concrete overlay and improve the pavement on northbound lanes of Hwy 169 between St. Peter and Le Sueur (about 10 miles).

Traffic impacts

  • None at this time.
  • No detour for Highway 169 traffic expected.
  • When construction starts in 2018, northbound and southbound Hwy 169 traffic will be reduced to a single lane in a head-to-head configuration, similar to the traffic configuration when Hwy 169 northbound is flooded by the Minnesota River.┬áThe Hwy 169 northbound exit and entrance ramps at the Hwy 93 interchange will be closed with detours provided.

Summary of work

  • Concrete pavement overlay of the Hwy 169 northbound lanes
  • Hwy 169 northbound bridge replacement over Robarts Creek (just north of St. Peter)
  • Culvert replacement/repair
  • Culvert sediment clean out
  • Sedimentation basin construction to capture sediment before it enters culverts under Hwy 169
  • Guardrail upgrades
  • Adding high tension cable median barrier corridor wide to protect against median crossover head-to-head accidents
  • Grading to improve drainage patterns and roadway side slopes
  • Interchange lighting at the Hwy 169/Hwy 93 interchange in Le Sueur
  • Adding Dynamic Message Signs to provide traveler information
