Columbus city council president Andrew Ginther is throwing his weight behind a proposal to redevelop Cooper Stadium into a racetrack.
Ohio plans to build a sound barrier made out of soil and plants in the state’s first eco-friendly attempt at muffling highway noise. State transportation department spokesman Scott Varner says the wall will be about 12 feet high.
Work crews are installing more noise walls on the city’s north side. The pre-cast barriers are being put up around Sharon Woods Metro Park near the Interstate 270 and 71 interchange. Much of the north side from Easton on the east to the Sawmill road interchange on 270 and on I-71 north of 161 is now walled in. The Ohio Department of Transportation says barriers are designed to reduce traffic noise but some northeast side residents say they make little difference.
With nearly seven million passengers moving through Port Columbus International airport every year, the jarring sound of airplane noise may be painfully familiar. NASA expects U.S. air traffic to double or triple by 2025, a projection that has engineers working hard to silence the roar. Engineers at Ohio State University have applied for a patent on technology called plasma actuators that could reduce jet noise.
