Commuter Route Information:  

(No changes)

  • Traffic through the intersection of 41st Street and Sycamore Avenue will be reduced to one lane of traffic in each direction with pedestrian crossing detours.  Traffic will be maintained at all times during construction.
  • Reconstruction of the intersection of 33rd Street and Sycamore Avenue will be completed between May 31, 2022 and August 5, 2022 to reduced impact to school traffic.  33rd Street will be closed to east/west traffic during this timeframe.  North/south traffic on Sycamore Avenue will be reduced to one lane in each direction. 
  • Individual lanes on Sycamore Avenue and side streets off of Sycamore Avenue will be closed intermittently to make curb and gutter repairs and to construct new accessible curb ramps.  Side street closures will be limited in duration, and no two consecutive side streets will be closed simultaneously.
  • The asphalt resurfacing of Sycamore Avenue will be divided into two phases (north of 41st Street and south of 41st Street).  The two resurfacing phases will not take place concurrently.  One lane of traffic in each direction will be maintained on Sycamore Avenue during resurfacing.
  • Every effort will be made to minimize travel impacts to local residents throughout the duration of the project.  Access to adjacent businesses and residences will be maintained at all times.
