Also, the Mackinac Bridge has stiffer trusses, allowing to reduce wind resistance and to support the weight of the bridge’s deck. The deck of the Mackinac Bridge is slightly more curved and provides lift in a cross wind (allowing more vertical airflow), making the roadway stable up to wind speeds of 150 miles per hour. At the time the Tacoma Bridge was built, little was known about aerodynamics and wind dynamics, which may have lead to the falling of the bridge. The Tacoma Bridge was known to have some aerodynamic instability after construction, but the architects failed to notice this during the bridge’s
