Tertiary Highway 715

Tertiary Highway 715 (T715) is a 2.21 kilometer Tertiary Highway located in the city of Cacklington and the township of Oakton, Cape Pleasant. The road serves as the main artery for the entire Cacklington Plateau, and since 1971 has consisted of the Plateau Expressway for the easternmost 1.21 km (of which 0.69 km are multiplexed with P295). Despite the functional classification as an expressway, however, the road features only one grade-separated interchange and frequent at-grade intersections.

Route Description
T715 follows the Plateau Expressway through Cacklington and becomes Oakton Avenue near the Oakton township line.

Plateau Expressway
From east to west T715 begins at an intersection with T787 (Industrial Boulevard) near the eastern end of the Cacklington Plateau and the Cacklington / Blackwolf Marina city line. It runs north for a block along an unnamed avenue that collects traffic onto the Expressway, which runs west from here through the predominantly industrial portion of the Plateau before interchanging with P295 at kilometer 0.52. Full access is provided to both directions of P295, with traffic defaulting onto P295 westbound (though P295 is not signed with any directions, the roadway follows an east/west course at this point). Continuing west, the Expressway parallels the Plateau Rail Link and intersects T787 four times, along with Plaza Drive, before T715 splits from it at the final intersection. T715 then multiplexes with T787 for a very brief 0.16 km before splitting off to the north on Oakton Avenue.

The entire Plateau Expressway carries a speed limit of 75 km/h.

Oakton Avenue
After splitting off from T787 and negotiating several sharp curves through a developed area, T715 reaches the township of Oakton and widens into a four-lane avenue. The road maintains this configuration and passes through a suburban neighborhood before intersecting Aydevlin Boulevard and then S84, the Northern Heights Expressway, at which it ends. Like most Tertiary Highways, T715 is maintained by the state in the unincorporated township of Oakton.
