the original design which didn't change for 95% of the entire highway, was to be a full freeway with full interchanges and 0 intersections.

I have posted the following previously, but again from the documents filed at the BCEAO regarding the functional design/design criteria for the SFPR (page 94):
Quote:
Table 4.2 Highway and structure design criteria / standards for the SFPR.
Design Criteria Four-lane rural design standards
Deltaport Way – 176th Street
Highway classification RAD (Rural Arterial Divided)
Design speed 80 km/h
Posted speed 80 km/h

Again, a Rural Arterial Divided functional design is below a Rural Expressway Divided design, which in turn is below a Rural Freeway Divided design.
I would have preferred a Rural Expressway Design standard with a 100 km/hr+ design speed upgradable to future freeway standard akin to Hwys 1, 99, and 91 and former 17. The SFPR is more akin to the SKS with tight geometry and "mini-changes" at Tannery Road, for example.
That said, an 80 km/hr design speed still has enough geometrical allowance to drive same safely at 100 km/hr.
