Southbound Stone Avenue will be reduced to one lane between Pennington Street and Broadway starting at 8 p.m. tonight.
The restrictions will allow the contractor working on the streetcar line to pave the intersection at Broadway and Stone Avenue.
Motorists will still be able to make any necessary turns off Stone.
The city recommends using southbound Church or Sixth Avenues as alternate routes.
All lanes on Stone Avenue are expected to open up by the end of the day Friday, July 12, 2013.
