Nik Wallenda, 35, achieved the two skyscraper crossings without a safety net or a harness.
He first walked up a steep incline between buildings either side of the Chicago River.
Then, blindfolded, Nik Wallenda crossed between the two Marina City towers.
It took him 6 minutes 52 seconds to complete the first stage 500ft above the ground – in winds that were gusting at up to 25mph.
Nik Wallenda then completed the 94ft between the two Marina City Towers in one minute 17 seconds.
The stunts were televised with a 10-second delay in case he fell.
On the ground, thousands cheered Nik Wallenda.
The tightrope walker – again blindfolded – then answered reporters’ questions.
Nik Wallenda, a seventh-generation tightrope walker, has already walked across both the Grand Canyon and the Niagara Falls on tightropes.
