Eric Anderson, 25, said he was considering his proposal options when he noticed the Sheridan Road and Surf Street bus shelter used almost every day by his girlfriend, Rachel Clark, 28, had available ad space, the Chicago Tribune reported Tuesday.
"At first I was afraid it wouldn't be very romantic -- it's a bus station," he said. "But I mentioned it to her sister and my cousin, and they were both excited about it. I had two women who liked it, so I went with it."
Anderson said he contacted JCDecaux, the company that manages Chicago's bus shelters, and officials agreed to rent him the ad space for one week at a discounted rate, the newspaper reported.
"Rachel! I love you! Let's be a team forever! Will you marry me? XOXO, Eric," the message read.
"I was lost in my own little world," Clark said, recalling her experience at the bus stop Wednesday. "I marched up to the bus stop, and he was standing behind it. ... He's like, 'Read the sign!' I started giggling and laughing going, 'Yes, yes!'"
