The second county branch in the library system opened in 1967 as the Westlane Branch in the Westlane Shopping Center on North Michigan Road. In 1974, the library purchased 2.76 acres on Zionsville Road from MSD Pike Township for the construction of the current 13,000-square-foot Pike Branch, which opened in 1986. Its design was cited by the local chapter of the American Institute of Architects. The branch was remodeled and expanded to 20,000 square feet in 1999. A 2025 renovation included:

• The Branch will be seeking LEEDv4 Silver Certification for energy and resource conservation.
