Many years ago, the Iowa Alpha Chapter of Tau Beta Pi adopted a two-mile stretch of Lincoln Highway on the west side of Ames. The Chapter continues to maintain this section of highway each semester. The clean-up generally takes place on a Sunday afternoon late in the fall and spring semesters when temperatures are relatively moderate. This semester the Adopt-A-Highway community service project took place on Sunday afternoon, 18 April 2021. The amount of trash collected was much larger than normal since the Adopt-A-Highway program had been suspended by the Iowa Department of Transport for over a year due to the Coronavirus and Iowa Alpha had not cleared its section of the highway for 18 months.
