They were made at the beginning of the Great Depression
From Cleveland Historical:
The Lorain-Carnegie Bridge opened in 1932, becoming the second fixed high-level span in Cleveland. It was built in part to relieve traffic on the Detroit-Superior Bridge (the citys other fixed high-level bridge) which opened in 1917. Construction began on the bridge in 1930, though plans for the bridge date as far back as 1902, when citizens of Cleveland presented a petition requesting construction of a high-level viaduct between Lorain and Central Avenues. In 1927, the city approved a bond issue of $8 million dollars for the bridges construction, changing the plan slightly to have the east approach connect with Carnegie instead of Central Avenue. Upon completion, the bridge stood 93 feet above the Cuyahoga River and had a span of 5,865 feet.
Despite frugal measures during the onset of the Great Depression, construction went on.
