  4. I-90 (Section 2 & 3) AGENCY ROLES PennDOT: To provide a sustainable transportation system and quality services that are embraced by our communities and add value to our customers. FHWA: Ensure compliance with regulations - National Environmental Policy Act (NEPA) - National Historic Preservation Act (Section 106) - Design Standards and Process Funding: Project Design – 100% State ($0.9m) - Construction – 100% Federal ($50.5m) -

  5. I-90 (Section 2 & 3) PURPOSE AND NEED Project Purpose: The purpose of this project is to address the identified deficiencies of I-90 , Section 2 and 3 that impede mobility, safety, and long-term cost effect maintenance of the highway facility. Project Need: The need for this project has been developed based on the identified deficiencies of existing I-90 corridor including: • Narrow shoulder widths (I-90) • Low vertical clearance (I-90) • Poor roadway condition (I-90) • Guiderail Upgrades (I-90) • Poor condition of bridges • Poor condition of McKee Road & Bridge
