All oversize loads entering Cambridge, Idaho must conform to the requirements set by the Idaho Department of Transportation (IDDOT) and the Cambridge Department of Transportation (CAMDOT).

In general, any vehicle over 12 feet in width, 13 feet 0 inches in height, and within the super heavy weight class (over 271,672 lbs) should obtain an oversize load permit from the IDDOT and potentially additional permits from CAMDOT.

To navigate the complexities of Cambridge's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Cambridge Harbor and major construction zones along the the Cambridge Financial Center area.

Idaho law mandates escort vehicles for any load exceeding 16 feet in width or 13 feet 0 inches in height. When traveling through Cambridge, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Cambridge Department of Transportation requires a minimum of 33 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Cambridge.

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

Required documentation for Cambridge 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.

Cambridge has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Cambridge Winter Marathon and the the Cambridge Sports Games, which may impact routing and scheduling.

Certain neighborhoods, such as Cambridge Center and areas around Cambridge Shopping District, 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 Idaho 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 Cambridge, Cambridge 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.
