Electric contractors started construction work on the WSU electric power distribution system Monday.

WSU Construction Manager Brian Funke said contractors will remove an old feeder tunnel. The construction is planned to last until approximately the second week of June.

Areas effected by construction are the north and south sides of Grimes Way and Alumni Way to Terre View Drive, he said.

Funke said construction will not have any impact on those driving on the streets, but pedestrians will be affected by the project.

He said there will be barricades and construction cones along the sidewalks to make safe paths for pedestrians to walk. Construction signs will provide detour instructions.

The feeder tunnel will be replaced because it has aged and began to wear, Funk said.

Feeder tunnels age just like anything else, he said, and replacing this one was high on the list of things that needed to be done.
