All oversize loads entering St. Mary's, Colorado must conform to the requirements set by the Colorado Department of Transportation (CODOT) and the St. Mary's Department of Transportation (ST.DOT).

In general, any vehicle over 11 feet in width, 15 feet 0 inches in height, and within the super heavy weight class (over 270,421 lbs) should obtain an oversize load permit from the CODOT and potentially additional permits from ST.DOT.

To navigate the complexities of St. Mary's's infrastructure, it's crucial to plan routes that avoid sensitive areas like St. Mary's International Airport and major construction zones along the the St. Mary's Harbor area.

Colorado law mandates escort vehicles for any load exceeding 17 feet in width or 14 feet 6 inches in height. When traveling through St. Mary's, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The St. Mary's Department of Transportation requires a minimum of 50 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of St. Mary's.

The Colorado Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from St. Mary's Department of Transportation for transit through St. Mary's limits.

Required documentation for St. Mary's 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.

St. Mary's has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the St. Mary's Music Parade and the the St. Mary's International Convention, which may impact routing and scheduling.

Certain neighborhoods, such as St. Mary's Center and areas around St. Mary's Hills, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.

The base permit fee for an oversize load in Colorado is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within St. Mary's, St. Mary's Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
