Chicago Bridges Facts ๐:@borntoseephoto Repost from @nowenchicago Follow ๐ ๐บ๐ธ@conexao.america for more photos Alliance @america_states @enjoy_la The City of Chicago maintains thirty-seven moveable bridges. Thirty-two are on the Main, North, and South branches of the Chicago River; five are on the Calumet River. Downtown bridges open approximately 100 times a year from April to November. Calumet River bridges open 5-6,000 times each year for freighter vessels and watercraft. Bridge openings take eight to ten minutesโfrom the time the gates lower to the moment traffic is clear to cross. The amount of time depends on how many vessels need to pass. #conexaoamerica #chigram #lifeofchicago #lifeofadventure #chi_shooters #city_features #likechicago #windycity #passionpassport #ig_color #timeoutchicago #thingstodoinchicago #bestofchicago #chicago_citylife #chicago_usa #chicago #chicago_people #primeshots #fromwhereidrone #fromwhereiride #dronephotography #northavenuebeach #lakemichigan #chicagolakefront #nowenchicago #chicago #chicagoriver #chicagobridges #chicagoriverwalk https://www.instagram.com/reel/CTP6K5vnK1l/?utm_medium=tumblr
