Boston philanthropists Peter and Carolyn Lynch have pledged $500,000 toward the construction of a skate park in Boston. The challenge grant, contingent on the Charles River Conservancy raising $100,000 more from other donors, will bring fundraising for the $2.3-million project to more than $2 million. The park will sit on land in Cambridge that the Big Dig construction made available along the Charles River. Skate park designer Zack Wormhoudt collaborated with local skaters to create the layout, which will include features similar to those at the Copley Square fountain and Boston Medical Center, popular destinations for skaters. The 24-hour park will accommodate recreation like skateboarding, in-line skating and BMX biking.
