LISBON — Renovations at Lisbon High School are expected to be completed by Monday, when freshman arrive for orientation. All classes start Tuesday.

Superintendent Richard Green said Wednesday that while the contractor is still waiting for some materials, it will not delay the start of school.

Work completed so far in the $500,000-plus project includes new windows, insulation and handicapped access at the main entrance.

An open house will be held in October,  Green said.
