Maybe. The airport access may demand more than that, depending on the truck traffic in and out (though much of that may be using Upper James, for the warehouse/distribution centre properties east and north of the air field)

They could also just do simple diamond interchanges. I'd hope for a bridge over Book because that setup isn't ideal for trucks -- they either have to slow down for the light coming down the hill from the 403, or accelerate uphill if heading north from a stop at the intersection.
