View Scheduled Construction Lane Closures

To ensure that the needs of the traveling public are met today and into the future, it becomes necessary to rehabilitate, replace or improve certain components of the Thruway’s aging infrastructure. Several studies and projects are carried out each year that result in less traffic congestion, improved and more efficient toll lanes, an overall improved infrastructure and various other customer oriented improvements system-wide.

Various studies involving noise analyses, alternative feasibility, corridor and toll collection improvements, potential environmental impacts, and alternative energy projects help to develop a prioritized Capital Improvement Plan to address the structural, safety, capacity and operational needs of the Thruway. These studies eventually result in design projects to implement the necessary improvements.
