The Kansas Department of Transportation has stated that there are plans are to switch traffic to Phase 3A on Tuesday on US 77 at the I-70 intersection where construction has been under way.  KDOT Engineering Technician Senior Dave Kelley said in this phase traffic will be split from the current head-to-head condition on the east side of US 77, placing the southbound traffic on the west side of center. Northbound US 77 will remain in the lane currently being used. Both northbound and southbound lanes will be required to use temporary asphalt tie-ins throughout the length of construction to enable the interior sections of permanent pavement to be connected on the interchange.

Stop signs will be added to the northbound and southbound lanes where they intersect with the entrance and exit ramps to Interstate 70.

The westbound off ramp will carry two lanes of traffic, by which those traveling south on US 77 will need to be in the left lane and those traveling north on US 77 will need to be in the right lane.

Southbound US 77 will be carried in two lanes south of Lacy Drive. Motorists wanting to go west on Interstate 70 will need to be in the right lane, and those continuing south on US 77 will need to be in the left lane.
