Initially, written public announcements notes stuck in the bus stations on the street indicated that the works would last for 4 months (until beginning of February 2011).
Now it´s 2 months after the initial deadline and the works do not seem even close to being finished.
At least they covered the part of the announcement where one could read the estimated duration, so that now you can only see that the works started in October 2010, but there is not deadline anymore.
