Captain William Moore Bridge, cable-stayed bridge in Skagway, Alaska, United States

The Captain William Moore Bridge is a 300-foot asymmetric single-pylon cable-stayed bridge over Moore Creek Gorge on the Klondike Highway, about 17 miles north of Skagway. Its H-shaped pylon, anchored on the south bank, leans 15 degrees from vertical and carries three pairs of forward cable stays in a fan array supporting a 270-foot two-lane box-girder deck. Since 2019 it serves as a pedestrian walkway and wayside historic attraction.

Completed in 1976, the bridge established the first road link between Skagway and Whitehorse, which had previously been accessible only by White Pass railroad. This new route transformed land travel in the remote region.

The bridge is named after Captain William Moore, an early settler who worked as a pilot, prospector, trader, and riverboat captain in the Skagway area. His name remains tied to the town's early development and regional expansion.

Since 2019 the 1976 cable-stayed span has served only as a pedestrian walkway and wayside historic attraction, while motor traffic uses the buried replacement bridge about 150 feet west on the realigned Klondike Highway. The site lies roughly 17 miles (27 km) north of Skagway, so visitors reach it by road.

The bridge design includes anchors only on the south bank, allowing the north end to move freely during earthquakes. This asymmetrical approach lets the structure flex with seismic motion without sustaining damage.
