[/i]Vendors at the Maxwell Street Market and drivers who use the Canal Street viaduct at 16th Street will be affected by the bridge reconstruction that starts after the evening rush period Monday. Traffic will be reduced to one lane in each direction between 14th and 18th Streets during construction, CDOT said. In addition to rebuilding the 75-year-old viaduct, the roadway will be reconstructed. To accommodate the displacement of vendors at the Maxwell Street Market, the limits of the market are being temporarily expanded north and south on Canal and onto Taylor Street between Canal and Clinton Street.
