I-94 at US-31 and I-94 at I-196 Interchanges - Permanent Pavement Marking Design

The I-94 at US-31 and I-94 at I-196 Interchanges project is a crucial segment of the St. Joseph Valley Parkway, completing the freeway connection to the Indiana-Michigan state line. This project includes the design of permanent pavement markings for the mainline I-94 freeway, the I-94/US-31/I-94BL interchange, the I-94/I-196 interchange, and the proposed and reconstructed bridges. The total length of the mainline freeway involved in the project spans approximately 3 miles.
Project Scope

• Freeway Interchanges and Bridges: Design of permanent pavement markings.
• Civil Engineering Aspects: Geotechnical investigation, Intelligent Transportation Systems (ITS), and maintenance of traffic (MOT).
• Environmental Considerations: Design concept development to avoid environmental sensitive areas like the Blue Creek Fen and enhance traffic safety.

Scope of work included:

• Preliminary Engineering:
  • Verification of design scope and cost.
  • Participation in Scope Verification meetings.
• Milestone Plan Submittals:
  • Incorporation of project-specific MDOT Standard Plans.
  • Attendance and incorporation of review comments from Milestone Review meetings.

• Deliverables:
  • Preliminary, Pre-OEC, OEC, and Final permanent pavement marking plan sheets.
  • Engineering cost estimates and miscellaneous quantities for permanent pavement marking design.
  • Reference Information Documents (RID) and selection of Special Provisions related to Pavement Markings.
• Final Project Package Preparation:
  • Revisions as per MDOT Specifications and Estimates Department feedback.
