San Francisco Airport (SFO) has announced the closure of runway 28L for 20 days in order to construct a new base layer below the runway surface.
Construction crews have begun the process of removing the existing layers of the runway, which is expected to reopen on Friday, September 27, 2019.
SFO has said it is expecting an increase in traffic volume during the 20-day construction period, as construction trucks need to access the area around the runway to deliver materials and remove old pavement.
Up to 600 trucks are expected in a 24-hour period at the peak of activities on the project, which is federally funded at a total cost of more than $16 million.
Total flights at the airport have been reduced by 13 per cent, as airlines collaborated with SFO to lessen their flight schedules so as to reduce the length of delays.
Even with this adjustment, flight delays are expected to average 30-45 minutes and so SFO has advised passengers to try to choose early morning flights before 9:00 am – a period which is not expected to see any delays.
