The Alaska Department of Transportation and Public Facilities is accepting sealed bids through May 1 for major improvements to runways and taxiways at Lake Hood Seaplane Base in Anchorage.

The project will repave two aprons used by seaplanes, surface seal another apron and two taxiways, and replace all painted runway markings. Workers will also replace a large culvert under one of the taxiways. The state estimates the work will cost between $2.5 million and $5 million.

Lake Hood is the world's busiest seaplane base, handling thousands of flights each year from pilots flying to remote Alaska communities and wilderness areas. The improvements are designed to maintain safe operations as the facility ages.

Bids must be submitted by 2 p.m. on May 1, 2026, at the department's office at 4111 Aviation Avenue in Anchorage. The winning contractor must complete all work by August 31, 2027.
