Collin County and Plano city officials are considering making State Highway 121 a toll road between the Dallas North Tollway and North Central Expressway, but a decision is still two years away. The option would place toll roads on three sides of Plano, but officials say it could ease traffic congestion by speeding up improvements to busy Highway 121 on Plano's northern edge. With the President George Bush Turnpike on the south and the Dallas North Tollway on the west, Plano Mayor Jeran Akers said he isn't thrilled with the prospect of having another toll road. The most important thing is that it be completed, and completed as soon as possible. The McKinney City Council adopted a resolution Tuesday in support of building the highway's main lanes as a toll road if funding for a tax-supported freeway isn't feasible in the near future.
