All oversize loads entering Union, Ohio must conform to the requirements set by the Ohio Department of Transportation (OHDOT) and the Union Department of Transportation (UNIDOT).

In general, any vehicle over 13 feet in width, 13 feet 0 inches in height, and within the super heavy weight class (over 205,111 lbs) should obtain an oversize load permit from the OHDOT and potentially additional permits from UNIDOT.

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

In Union, Ohio, loads wider than 16 feet or taller than 13 feet 0 inches must be accompanied by certified escort vehicles. Additional escorts may be required based on the specific route and time of travel through urban centers.

Union regulations state that police escorts must be arranged at least 35 hours before transport for loads that will impact major thoroughfares or require temporary traffic control measures.

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

Required documentation for Union 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.

Union has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Union International Exposition and the the Union Spring Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Union and areas around Union Lake, 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 Ohio 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 Union, Union 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.
