All oversize loads entering Bangor, Maine must conform to the requirements set by the Maine Department of Transportation (MEDOT) and the Bangor Department of Transportation (BANDOT).

In general, any vehicle over 12 feet in width, 14 feet 0 inches in height, and within the super heavy weight class (over 295,311 lbs) should obtain an oversize load permit from the MEDOT and potentially additional permits from BANDOT.

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

Escort vehicles are required for oversize loads exceeding 16 feet in width or 14 feet 0 inches in height on highways and certain city streets. The Maine State Police often require escorts for loads that are particularly large or heavy.

For movements within Bangor, the Bangor Department of Transportation may mandate police escorts for oversize loads, especially during peak traffic hours. Scheduling these escorts requires advance notice, typically at least 32 hours prior to the move.

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

Required documentation for Bangor 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.

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

Seasonal restrictions apply during major events like the the Bangor Music Festival and the the Bangor Holiday Exposition, which may impact routing and scheduling.

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