Chapter 550 Freeway Access Revision
Reason for revision:

  • FHWA Interstate Access Policy update May 2018 prompts this revision.
  • This chapter will replace the existing Chapter 550.
  • Policy applies only to freeways.
  • Access breaks to all other limited access highways administered via Chapter 530.
  • New chapter 550 provides details about environmental and planning disciplines, process, outputs and engagement.
  • The new term for IJR is ARR. ARRs address operations and safety
  • The required NEPA/SEPA document is needed before final approval of an ARR.
  • Prior to preparing the ARR, an Off-system Feasibility Study is conducted to seek improvements that meet performance needs.
  • If off-system study does not resolve performance need, the ARR is prepared to include and analyze on-system freeway improvements

The Design Manual Revision Process
Design Manual chapters currently planned for revision are listed in the tables above.

  • When a draft chapter is ready for WSDOT Region and Area review and comment, a "Review Draft" is posted in its respective table and designated points of contact are notified.
  • The points of contact then download the chapter file and distribute to people in their region/area.
  • Tables show the comment review period (usually 4 weeks).
  • Points of contact collect comments and send back to HQ Design Office. Those comment files are posted in the tables as they are received.
  • After evaluating all comments, the Design Office posts a file showing the final draft for approval, with all comments and the HQ Design Office's response to them. Not all comments are used, but all are considered.

When a chapter has "final approval," it will be available for use prior to publication. See the link in the right-hand column of each table as chapters are approved.

Region "Points of Contact" (POCs)
WSDOT regions have identified specific people to act as POCs to coordinate a unified region response to draft policy changes.

  • POCs coordinate with people in their region to review/comment on draft policy.
  • POCs send their region's comments back to HQ in one document.
