HOUGHTON — The Portage Lake Lift Bridge connecting Houghton and Hancock will be undergoing more work next week.

Michigan Department of Transportation officials say their contractor will be performing test lifts on the bridge span, requiring brief closures of the structure. Delays of ten to fifteen minutes — roughly equivalent to a standard bridge lift for boat traffic — should be expected throughout the day and possibly even during nighttime hours.

Traffic will be allowed to clear and resume normal flow between test lifts.
