SIGNS, FLAGS, & LIGHTS
“Oversize Load” signs are required front and rear for all oversize loads. They are not required and should not be used for overweight-only loads. Flags are required at all four corners of any extremity for wide and over-length loads, and at the end of load projections greater than 4 feet.
The curfew times shown on the addendum need to be accompanied by an oversize permit. When traveling through the Eisenhower Tunnel on I-70, the maximum overall height allowed is 13’11”. Higher loads use US-6 to bypass the tunnel. Permitted loads over 11′ wide must pull over and call to get clearance to pass through the tunnel.
Meanwhile, wider loads are able to pass through without extra notice. Loads going in and out of Denver require permits for city streets. However, Denver is especially slow in turning them around (an average wait of 2-3 days). Plan accordingly.
