This weekend, Oct. 21-22, a crane will be positioned along 41st Street between Huntington and Washington avenues in front of Bldg. 520 and Bldg. 521 to perform maintenance. As a result, the street will be temporarily closed to vehicular traffic (7 a.m. on Saturday, Oct. 21, through 7 p.m. on Sunday, Oct. 22). Employees who need to access Bldg. 520 or Bldg. 521 during this timeframe, will still be able to do so.
