Access to SIMPCO/SRTS from US 20 closes 3/18/2024

Drivers on U.S. 20 east of Sioux City in Woodbury County need to be aware of lane closures that may impact their trip beginning at 7 a.m. on Monday, March 18, 2024, until Nov. 22, 2024, weather permitting. On Monday, March 18, weather permitting, crews will shift westbound U.S. 20 traffic onto the eastbound U.S. 20 lanes in a head-to head traffic pattern so work can be done of Stage 2 of reconstruction of the westbound lanes of U.S. 20. Until the project is complete, you won’t be able to make left turns while traveling in the work zone.

There will be one lane access available on the eastbound and westbound lanes until the official work begins on March 25.  The head-to-head traffic (east and west) starts March 25 on the eastbound lane until the construction is completed.

There are only two access points to the facility:

  1. From North, South and West: Gordon Drive to 4301 Stone Avenue (Casey’s General Store) to continue north on Stone Avenue which turns left into 155th until reaching Benton Avenue. Turn Right on Benton Avenue and turn left to the north entry of DOT and SIMPCO/SRTS Facility.
  2. From East (Hwy 20): Turn right on Charles Avenue from Hwy 20, left on Correctionville Road, to left on Buchannan Avenue, then right on 155th to left on Benton Avenue. Turn left to the north entry of DOT and SIMPCO/SRTS Facility.

Help keep everyone on the road safer. Drive with caution, obey the posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, you should stay alert, allow ample space between vehicles, and wear seat belts.
