Motorists are urged to use caution in the construction zone and to choose an alternate route in advance.
These road closures are part of NTTA’s interchange construction project which is prompting a series of overnight closures that will occur each weeknight in August. Depending on the contractor’s schedule, a different combination of main lanes and/or frontage roads will be closed each night. Daily updates of each closure are available on www.ntta.org by clicking on “general lane and ramp closures” and the City of Frisco will announce each night’s closure as the information becomes available.
