All oversize loads entering Lambert, Missouri must conform to the requirements set by the Missouri Department of Transportation (MODOT) and the Lambert Department of Transportation (LAMDOT).

In general, any vehicle over 13 feet in width, 14 feet 0 inches in height, and within the super heavy weight class (over 187,970 lbs) should obtain an oversize load permit from the MODOT and potentially additional permits from LAMDOT.

To navigate the complexities of Lambert's infrastructure, it's crucial to plan routes that avoid sensitive areas like Lambert College Campus and major construction zones along the Lambert Shopping District area.

Missouri law mandates escort vehicles for any load exceeding 16 feet in width or 15 feet 0 inches in height. When traveling through Lambert, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Lambert Department of Transportation requires a minimum of 29 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Lambert.

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

Required documentation for Lambert 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.

Lambert has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 3-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Lambert Music Parade and the the Lambert Music Exposition, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Lambert and areas around Lambert Research Park, 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 Missouri 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 Lambert, Lambert 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.
