Exception summary

Installation drawings and update to special provision 107S06 to allow the use of the Traffix Delta crash cushion as an option on MTO contracts.

Why consultation isn't required

A formal consultation took place in August 2021 before implementation of the TCP and additional
targeted consultation was subsequently implemented to address comments.


MTO has conducted extensive targeted advance consultation with internal staff and with roadside
safety contractors represented by the Ontario Road Builders' Association (ORBA) through its
Roadside Safety Subcommittee. Further consultation through the TCP is not required because no
objections have been brought forward to MTO through targeted consultation with all impacted
stakeholders on the proposed modification of the existing attenuator specification or introduction of
new standard drawings.

Exception details

The modification to Special Provision 107S06 introduces the Traffix Delta crash cushion as a TL-3 option for use on the upstream end of a concrete barrier.


Four new MTO drawings provide configurations for temporary, permanent, unidirectional and bidirectional installations.
