Greenville’s new pedestrian tunnel under M-57 has received the 2011 Outstanding Civil Engineering Achievement Award from the Michigan Section of the American Society of Civil Engineers.
The new handicap-accessible tunnel is the final link in Greenville’s 6.5-mile Fred Meijer Flat River Trail, which circles the city and includes a spectacular, three-mile-long stretch next to the scenic Flat River.
The 150-foot concrete tunnel is 16 feet wide and 12 feet tall. It passes under M-57 in Greenville at the intersection with Maplewood. The tunnel includes concrete traffic-safety barriers on the road above to keep pedestrians safe, and electronic, aluminum gates at each end of the tunnel to close it during the night. Prein&Newhof designed the tunnel and assisted Greenville’s staff during its construction.
The tunnel interior is decorated with 530 tiles hand-made by local artists of all ages. The tiles depict Greenville’s history and include impressions of items found in archeological digs in the area.
