Bienfait. With portions of it being paved or gravel, it is approximately long. Hwy 605 begins in the
Rural Municipality of Coalfields No. 4 at an intersection with Hwy 18 just east of the town of Bienfait, immediately crossing
Canadian Pacific Railway's Estevan subdivision as it heads north as a paved two-lane highway across rural farmland to have an intersection with
Hwy 704 and enter the
Rural Municipality of Browning No. 34, having an intersection with
Hwy 700 and entering the town of
Lampman. It crosses
Canadian National Railway's Lampman subdivision as it travels through an industrial area before making a right at the Lampman Golf Club, joining a
concurrency (overlap) with
Hwy 361 eastbound as the pair travel along Corrigan Road to cross the same railway line again and traverse neighbourhoods along the south side of downtown. At the eastern end of town, Hwy 605 splits off and heads north, crossing the same railway line for the third and final time as it leaves Lampman and travels to the west of
Browning, where it traverses a switchback and enters the
Rural Municipality of Brock No. 64. The highway passes through rural areas, where it crosses
Moose Mountain Creek to enter the village of
Kisbey, travelling along the western side of town along King Street to have a junction with
Hwy 13 (

Moose Mountain Upland, with the asphalt transitioning to gravel at the intersection with Township Road 92. Hwy 605 travels through the
Pheasant Rump 68 First Nation Reserve, where it crosses into the
Rural Municipality of Hazelwood No. 94 and travels through the community of
Warmley, prior to going through a switchback winding its way through mostly wooded terrain, where it crosses
Hwy 711 and travels to the west of the hamlets of
Hazelwood and
Bekevar. Lowering back down off of the upland, Hwy 605 enters the
Kingsley No. 124 and traverses through rural farmland for the next several kilometres to temporarily gain asphalt again as it travels through the eastern side of the town of
Kipling, where it crosses
Hwy 48, crosses Canadian National Railway's Cromer subdivision, passes by the
town's airport, and shares a short concurrency with the western end of
Hwy 709, before leaving the town and continuing north along gravel. The highway heads north through rural areas, traversing a switchback (where it has an intersection with
Hwy 703) and crossing
Pipestone Creek, before entering the
Rural Municipality of Elcapo No. 154 and crossing a
causeway / bridge over
Ekapo Lake. Entering the town of
Broadview at the intersection with Rideau Street, it regains asphalt again as travels through neighbourhoods along Sixth Avenue to enter downtown, where it makes a left turn onto Main Street and then a right turn onto Ninth Avenue, where it crosses under the Canadian Pacific Railway's Broadview subdivision and makes a slight right onto Qu'Appelle Road. After crossing
Hwy 1 (
Trans-Canada Highway), Hwy 605 immediately makes a left turn as it leaves the town behind, running parallel to the Trans-Canada for a couple of kilometres before curving back northward and winding its way through portions of the
Kahkewistahaw First Nation reserve and
Cowessess 73 as it lowers down into the Qu'Appelle Valley, crossing the
Qu'Appelle River into the
Rural Municipality of Grayson No. 184. It immediately crosses
Hwy 247 just west of
Sunset Beach and climbs its way back out of the valley, heading due northward through rural farmland for the next several kilometres to travel along the eastern side of the village of
Grayson via Mission Road (which is paved), where it has an intersection with
Hwy 22. Continuing on, the highway enters the
Rural Municipality of Cana No. 214 along Cana Road, travelling along the eastern side of the hamlet of
