All oversize loads entering South Hills, Montana must conform to the requirements set by the Montana Department of Transportation (MTDOT) and the South Hills Department of Transportation (SOUDOT).

In general, any vehicle over 12 feet in width, 16 feet 6 inches in height, and within the super heavy weight class (over 284,442 lbs) should obtain an oversize load permit from the MTDOT and potentially additional permits from SOUDOT.

To navigate the complexities of South Hills's infrastructure, it's crucial to plan routes that avoid sensitive areas like South Hills Commercial Zone and major construction zones along the South Hills Civic Center area.

The Montana Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from South Hills Department of Transportation for transit through South Hills limits.

Required documentation for South Hills permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

South Hills has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the South Hills Sports Games and the the South Hills Historical Show, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown South Hills and areas around South Hills Basin, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
