Update: In a release Friday afternoon, the Department of Transportation announced it has closed all northbound lanes of the Seward Highway at the Tudor Road overpass. It will remain closed through the weekend and possibly into next week as DOT crews continue to make repairs. Motorists are asked to follow detours in the area and to use alternate routes if possible. Original Story: Some lanes are going to open for morning commuters navigating detours and delays due to a damaged overpass in midtown. A dump truck heading northbound on the New Seward Highway slammed into the Tudor Road overpass shortly after midnight Thursday morning, forcing the Alaska Department of Transportation to replace a girder hit by the truck's raised bed. Anchorage Police wrote in a release Friday morning that two eastbound lanes will open for the commute but there will be no eastbound to northbound turn for Seward highway traffic. In addition, police wrote Southbound lanes of the New Seward are okay for travel but northbound will remain closed to one lane while crews work on the Tudor overpass. Drivers are asked to obey traffic cones and signs in the area.
