The branch will remain closed for two to four weeks.
During this time, temporary walls will be built in preparation for expansion and remodeling.
The library's director says this is 'phase one' of a project that will increase the space in the library by thousands of square feet.
She says while the library will be closed, staff will still be on the clock prepping books and other materials so construction crews can come in.
Meanwhile, other Thomas County branches will still be open. For a complete list of libraries in the system, visit www.tcpls.org
