The Northern Avenue Bridge has a vertical clearance in the closed position of 7 feet at mean high water and 16 feet at mean low water. The existing drawbridge operation regulations are listed at 33 CFR 117.599.
The owner of the bridge, the City of Boston, requested a temporary deviation from the drawbridge operation regulations to facilitate replacement of the submarine power supply cable at the bridge. The old power supply cable failed and until it can be replaced the bridge must temporarily operate using an electrical generator.
Additional time is necessary for bridge openings as a result of the use of the temporary generator in order to start and adjust the generator voltage prior to opening the bridge. A one-hour advance notice is necessary to allow sufficient Start Printed Page 56374time for the bridge operator to open the bridge after a request is given.
