The completion date for Beersheba Street Bridge replacement could be pushed back eight months due to problems with construction.According to TDOT spokesperson Jennifer Flynn, Simpson Construction has submitted a change order and is asking for a new completion date of May 31, 2012.“The change order is in the works, so it’s not official yet, but I believe that’s what they are asking for,” Flynn said of the new date.Simpson Construction was awarded the $5.7 million project in September 2009 to replace the existing bridge. A completion date of September 2011 was set. Since the project began, complications have slowed work considerably.
