King Road Is Being Widened From Two Lanes to Four — Here's Where Things Stand

If you drive King Road between Witt Road and Rose Lane — cutting through Hackberry, Little Elm, or into Frisco — you are already inside an active construction zone. The county held its groundbreaking on Feb. 25, 2026, and crews started work in March.

The project converts a two-lane rural asphalt road into a four-lane urban corridor. Between Witt Road and Anthem Drive, it goes to four lanes. Between Anthem Drive and Rose Lane, three lanes with a center two-way left-turn lane. That reconfiguration matters if you regularly make a midblock turn — the geometry of the road will look noticeably different when it's done.

Denton County, the City of Frisco, the City of Hackberry, and the Town of Little Elm are all sharing the cost, with Denton County contributing bond funds from its Transportation Road Improvement Program — money voters approved for exactly this kind of regional connector.

At one point during construction, westbound King Road from Witt Road to Rose Lane was closed, with eastbound traffic shifted to the north side of the existing pavement and westbound drivers detoured south on Witt Road and west on Stonebrook Parkway. Check the Frisco project page at friscotexas.gov for current lane-closure status before you drive it.

Completion is targeted for summer 2027, according to both the county's announcement and Frisco's project timeline. That's a roughly 18-month build from the March 9 start date, so drivers should expect the better part of another year of active work.

The stated goal is a faster connection to the Dallas North Tollway for residents moving between all three communities.
