This consultation was open from:
December 14, 2021
to January 14, 2022
The posting to seek public comments related to the 2+1 Pilot Project – Site Selection Criteria Report is now closed. 93 comments were received. As the result of some of the comments, the content of the Design Parameters Report will be updated.
On this page
The updates on the Design Parameters Report will include a typical cross section, clearer language for barrier selection and for recommended foreslopes and backslopes associated with the 2+1 roadside environment.
Comments and responses are attached. Where applicable, other ministry offices were made aware of the concern expressed in some of the comments.
The ministry is grateful for the reception of this initiative and looks forward to reaching out to the public during the class environmental assessment and preliminary design stage of the project.
Effects of consultation
The technical comments received required editing the draft report to address the issues identified in them.
Information on entrances and property owners to be affected by the addition of a median barrier to the highway will be passed to the project team for future action regarding mitigating measures.
The 2+1 roadway model consists of a three-lane cross-section with one lane in each direction of travel and the additional third lane alternating between directions of travel to allow passing opportunities and increased capacity. In other jurisdictions this concept has been found to improve operational efficiency and reduce collisions for selected two-lane highways. A flush narrow median and median barrier, which helps protect against cross-over collisions, are common features of the 2+1 Roadway concept.
The ministry has formed a 2+1 Advancement Working Group whose purpose is to research 2+1 roadway models to develop a variation of the model appropriate for Ontario highways.
The findings of the 2+1 Advancement Working Group are presented in two parts/reports. The first report, posted in the Technical Consultation Portal in September 2021, established parameters / criteria for the selection of potential candidate sites to pilot the model in Ontario. This second report presents recommendations for potential locations and design parameters for the 2+1 roadway model, including cross section elements, barrier types, and other design guidance.
