Buffalo Corridor Study

Introduction

The New York State Thruway Authority (Authority) and the New York State Department of Transportation (NYSDOT), in cooperation with the Federal Highway Administration, have initiated a Corridor Study on the New York State Thruway near Buffalo in Erie County. The Corridor Study is being conducted on I-90 between Interchanges 49 (Transit Road) and 53 (I-190) and on the Youngmann Memorial Highway (I-290) between (I-90) and Interchange 7 (Main Street). The purpose of this study is to develop a plan to address capacity, structural, safety, and operational needs for this section of the Interstate Highway System over the next 30 years.

The Authority and NYSDOT have been conducting a Corridor Study on eight miles of I-90 near Buffalo, between Interchange 49 (Transit Road) and 53 (I-190) and on the Youngmann Memorial Highway (I-290) between I-90 and Interchange 7 (Main Street) in Erie County (see map). The project includes engineering studies, environmental studies, and a public outreach program. The project involves the identification of the safety, structural, capacity, and operational needs and concerns that may occur over the next 30 years.

Specific areas that are being evaluated include:

  • Mainline mobility
  • Structural condition of Thruway/ DOT pavements and bridges
  • Congestion and access at Interchanges

The study will identify improvements needed to meet increasing traffic demands and projects that could be developed to meet these demands.

Potential improvements that will be studied include:

  • Reconfiguration of the I-90 interchanges with: I-290, NY 33, Walden Avenue, William Street and Transit Road
  • Reconfiguration of the I-290 interchange with NY Route 5 (Main Street)
  • Addition of a travel lane(s) in each direction

Other improvements may be studied as the Corridor's needs are analyzed. In the future, this Website will identify the needs and alternatives under consideration.
