The initial phases of the US 75 construction project that will affect traffic on the Plano Parkway overpass will begin next week, resulting in full lane closures along the major north-south highway, according to a Texas Department of Transportation spokesperson. Both north- and southbound lanes on US 75 will close starting 3 a.m. on Nov. 11, through 5 a.m. on Nov. 13, near the President George Bush Turnpike intersection, the spokesperson confirmed. The closures will roughly span from Plano's 15th Street to Renner Road in Richardson according to a map supplied by TxDOT. Parts access ramps from PGBT to 75 will also close. The closures are part of a broader project that involves demolishing and rebuilding the Plano Parkway bridge, as previously reported by Community Impact Newspaper. The reconstruction of the bridge will widen its support columns to allow room for additional lanes on the on- and off-ramps stemming from PGBT to US 75. The full project is expected to be last into 2019, a TxDOT spokesperson told Community Impact Newspaper in October.
