But again, the emphasis is for those people coming in from Monroeville and the other side of the city, the whole entire Parkway underneath us is going to be closed down, which is going to be quite a sight to be seen for that almost five-day period,' Pittsburgh Public Works Director Mike Gable said. 'We're working on all sorts of detours and we're going to modify and change the traffic signaling wherever necessary, working with CMU and our Public Safety Department. Joe Grushecky and the Houserockers will headline Saturday's Greenfield Bridgefest, a community party and a last bit of fun before the headaches begin. Then, come Monday, workers will begin dismantling as much of the deck as possible in anticipation of its ultimate demotion but not before a little celebration Friday night, the venerable old span will close down for good. We know it's going to be an inconvenience, but it's a 93-year-old bridge that needs to come down,' said Guy Costa, the city's operations director.Īt 10 p.m. ( photo by Pat Hassett.'It's a major link for motorist, pedestrians and bikers.

Maintain current service frequency where possible.Maintain Downtown & Oakland arrival/departure times as much as possible Work on the Greenfield Bridge will cause significant detours of four bus routes for about two years, starting on Sept.Avoid circuitous, difficult and confusing routings.Use the perceived least congested route.Maintain as much regular routing as possible.

Overall, our strategy for designing the detours included: We will continue to review the routes during the detour period to determine if additional changes should be made. It also allows both operators and riders to become familiar to the new routes and schedules sooner than motorists, which might help this transition. This is due to our regular quarterly service change starting on that date. The bus detours will start September 6th, about six weeks ahead of the bridge closing.

This will help buses remain on schedule and protect the reliability of the routes for riders. The detours will be implemented as a regular service change and be reflected in the timetables. The affected buses are (in numeric order): Work on the Greenfield Bridge will cause significant detours of four bus routes for about two years, starting on Sept. In dialog with riders and the Greenfield Community Association, Port Authority developed and published the detour maps and descriptions shown below: From Port Authority of Allegheny County: Greenfield Bridge Detour Routings, June 2015: ( Read the complete text here.)
