A southern section of Anchorage's Tony Knowles Coastal Trail will be closed for construction work next week.

From Tuesday, July 29, through Friday, Aug. 1, from 8 a.m. to 4 p.m., a 2.5-mile stretch of the Coastal Trail south of Point Woronzof will be closed to bike and foot traffic, the municipal parks department said in a release. Trail construction will be extending from the Anchorage Water and Wastewater Utility plant on Hutson Drive to the Sisson Bridge at mile 6.6.

Crews will be completing a surface makeover on the trail, finishing the last leg of a 7-mile repaving project that began last summer, said Maeve Nevins, project manager with Anchorage Parks and Recreation.

Because the trail is isolated, no detour route to or from Kincaid Park is accessible. Nevins said the parks department limited the hours of the closure to the daytime to accommodate weekday bike commuters.

The construction work is part of a multiyear trail improvement project for the Coastal, Chester Creek and Campbell Creek trails. The project is now in its second year, and Anchorage residents have likely seen other phases unfolding elsewhere on the trail system.

On Monday, for example, crews began repaving a mile-long corridor of the Chester Creek trail, extending from Westchester Lagoon to Valley of the Moon Park, Nevins said.

Unrelated to the construction work, a pedestrian bridge connecting Westchester Lagoon to downtown Anchorage that collapsed in mid-June is still closed. It's not clear from parks officials when the bridge will be back open.
