LauraLi Gilliam sailed over the mounded dirt of Spokane’s new BMX track on her 20-inch tires, christening the track with a herd of others on Saturday. The track is one of several new features added in the expansion of the $11 million, 76-acre Dwight Merkel Sports Complex near Joe Albi Stadium in north Spokane. The complex, on North Assembly Street, has six full-size grass soccer fields, two synthetic fields, five softball diamonds, a BMX track, a skate park, a splash pad and walking trails. In 2007, voters passed a park improvement bond that helped finance the expansion of the old facility. Construction started in 2008.
