The Tour de France comes to Essex on 7th July. While it won't run through Brentwood, it will run through Epping, meaning that Townlink 21 will not be able to run on that day.
All of Brentwood's other buses will be running as normal, but there could be some disruption due to traffic caused by road closures elsewhere in the county.
Check the Twitter feeds on the right for updates on the day. More details about the Tour de France in Essex can be found here.
