The $5 million project is part of a bond measure approved by voters in 2017. Construction began Nov. 8, according to a city spokesperson.
Improvements include the children’s area being renovated plus a new Digital Creation Space and an area being added for teenagers. Other additions include more meeting rooms; a new roof; and a new heating, ventilation and air conditioning system in the building.
"The renovation will occur in a phased approach with ongoing construction activity that might be disruptive," Plano Library Director Libby Holtmann said in an email. "Our staff is available and happy to assist in connecting patrons to resources and services."
Holtmann said Harrington library will remain open but recommended residents to visit the Schimelpfenig, Haggard or Parr libraries if needed.
Computer and printing services will be limited during construction and Harrington Library is not accepting donations currently, officials said.
As part of the same bond measure, Davis Library will be closed for construction starting Dec. 4.
"We are delighted that Plano residents voted to approve these two Bond projects in 2017," Holtmann said. "The additions to both libraries will benefit the community for years to come."
Harrington Library is located at 1501 18th St., Plano. More information on the library's renovations can be found here.
