The Portage Lake Lift Bridge (officially the Houghton–Hancock Bridge) connects the cities of Hancock and Houghton, in the US state of Michigan. It crosses Portage Lake, a portion of the waterway which cuts across the Keweenaw Peninsula with a canal linking the final several miles to Lake Superior to the northwest. US Highway 41 (US 41) and M-26 are both routed across the bridge. It is the only land-based link between the north (so-called Copper Island) and south sections of the Keweenaw peninsula. In June 2022, it was dedicated as a National Historic Civil Engineering Landmark.This moveable bridge is a lift bridge with the middle section capable of being lifted from its low point of four feet clearance over the water to a clearance of 100 feet (30 m) to allow boats to pass underneath. The bridge is the world's heaviest and widest double-decked vertical-lift bridge. More than 35,000 tons of concrete and 7,000 tons of steel went into the bridge, which replaced the narrow 54-year-old swing bridge, declared a menace to navigation on the busy Keweenaw Waterway.Hancock and Houghton hold an annual celebration called Bridgefest to commemorate the opening of the bridge which united their two communities.
