3.0 m for freeways and expressways (page 31)
The lanes are 2.4 or 2.5m wide. I have always known them to be around 8ft wide.
I agree, I wanted the multi-use path as part of the project but the MOTH is cheap and don't like cyclists. Only the right of way land space is being set aside as part of the project. City of Surrey or Delta will have to foot the bill for the actual pathway or try to reserve some of the Gateway cycling funding for it.

The Coquihalla and Okanagan connector are bike routes with a limit of 110 and the shoulder is 2.5 meters at the very most, and considerably less than that in some sections.
I am entirely sympathetic to the fact that getting people to cycle is a chicken and egg thing: you have to built the infrastructure first.
That said, the simple fact is the design speed is 90 km/hr and people are going to travel whatever they feel is safe.
"2.5 m for a posted speed ≥ 80 km/h and SADT > 10,000 vpd." If the shoulder is 8 ft / 2.5 metres, then it is, in fact wide enough for 90 km/hr.
3 meters would only be required for a "freeway" although it isn't specified here what that means as far as speed limit (100 km/hr? 110?) or traffic count (50,000? 100,000?).
I agree a multi-use path should have been constructed. Cycle traffic should not have been allowed on the roadway, as on highway 91. Lowering the limit artificially doesn't resolve those problems. Take a look at the sunbury intersection - 9 lanes wide and totally hostile to pedestrians and cyclists alike. Cycling beside big rigs on a truck route almost requires a bit of a death wish. I tried it on river road a few times and gave up.
River road and King road will be viable future alternatives once truck traffic is off those routes. The hill at 176th is tortuous anyway, so it's not like you can avoid the steep grade by taking SFPR.
