TDOT Contractor To Modify Traffic Patterns On Broad Street And Market Street Near I-24 In Chattanooga Friday, June 4, 2021 As part of the project underway to improve the I 24 interchanges at SR 2/Broad Street and SR 58/Market Street in Chattanooga, TDOT contract crews will soon modify the traffic patterns in the Broad Street and Market Street areas. These new traffic patterns will be in effect beginning after 9 a.m. on Monday. Currently northbound Broad Street traffic accesses I-24 East via 25th Street and Long Street. After the contractor completes the traffic pattern modification, the Long Street ramp will be closed. Traffic will be directed to use 26th Street and Market Street to access I-24 East from northbound Broad Street.
