Over the weekend construction began on the new bikeway meant to connect the heavily used trails along Buffalo Bayou west of Downtown with the Columbia Tap trail on Downtown’s east side — and from there to the trails along Brays Bayou and the Medical Center. The 2 blocks of Lamar St. between Smith and Bagby now have this green zone installed along their southern side, replacing curbside parking spaces on the one-way street. Additional construction is scheduled for every weekend between now and March 8, when the steadily growing green bike path will reach Discovery Green.
