SUPPLEMENTARY INFORMATION:

The new Groveland Drawbridge across the Merrimack River at mile 16.5, between Groveland and Haverhill, has 15.9 feet of vertical clearance at mean high water and 21.61 feet of vertical clearance at mean low water. The existing drawbridge operation regulations are listed at 33 CFR 117.605(c). The waterway users are and seasonal recreational vessels of various sizes.

The owner of the bridge, Massachusetts Department of Transportation (MDOT), requested a temporary deviation from the schedule to facilitate completion of this new bridge replacement project. Upgrades to the electric motor drive system must be undertaken between June and September that were not part of the original scope of work.

The bridge is presently manually operated pending upgrades to the drive system and requires a crew of seven to open and close the draw. During the final phase of construction the labor force will be less than seven laborers presently necessary to operate the bridge.

Allowing the bridge owner to require a twenty-four hour advance notice for bridge openings would provide sufficient time for the bridge owner to get the necessary crew members at the bridge to open and close the bridge.

The bridge rarely opens historically during the time period this temporary deviation will be in effect.

Under this temporary deviation the Groveland Drawbridge may require at least a twenty-four hour advance notice for bridge openings from June 21, 2014 through September 20, 2014. Requests for bridge openings may be made by calling the numbers posted at the bridge, [phone] or 1-800-227-0608. There are no alternate routes for vessel traffic to take; however, there have been few requests to open the bridge historically.

The Coast Guard will also inform the users of the waterways through our Local and Broadcast Notice to Mariners of the change in operating schedule for the bridge so that vessels can arrange their transits to minimize any impact caused by the temporary deviation.

In accordance with 33 CFR 117.35(e), the drawbridge must return to its regular operating schedule immediately at the end of the effective period of this temporary deviation. This deviation from the operating regulations is authorized under 33 CFR 117.35.
