🎶Greenfield Bridge is falling down🎶: Deconstruction of the Greenfield Bridge began this weekend by Mosites Construction and Development Company. The deconstruction of the bridge caused closures on I-376 inbound and outbound this weekend (not to mention backed up traffic) and will do so again in the future.
