And that's the Chelmsford Shuttles practically done! Took only 3 years for someone to actually update the routes...

(Ignore the larger than normal changeset area. Some additional routes had modified operator tags. Roads mentioned in the changeset are in or around Beaulieu Park.)

And the bustimes.org links...

Bus route 70 itself also needs correcting as it no longer operates east of Braintree East Tesco. https://bustimes.org/services/70-marks-farm-tesco-chelmsford-bus-stn

Line of route for the 17A and extended route 17 sourced from a bus operator publication (owing to SESX not publishing BODS data on this route at this present moment...): https://stephensonsofessex.com/wp-content/uploads/sites/48/2025/07/17-17A-07-25.pdf

I also intend to map route 333 soon...

I had actually forgotten to change the names of the X10 and X30 routes back. While mapping-out the routes, I used codes to denote if the routes were heading via different locations (BH for Broomfield Hospital, GD for Great Dunmow, GW for Great Waltham), as opposed to running directly between Stansted and Chelmsford. These have been corrected in changeset #168568254:
changeset/168568254

Because, yeah... highway=mini_roundabout

And now for the sources (and explanations):

Service 7A is a new route, operated by First Essex.
https://bustimes.org/services/7a-hadleigh-hockley#map

Routes 7, 21C, and 63 have changed operators:
- 21C and 63 from NIBSbuses to First Essex
- Certain services on the 7, formerly run by Stephensons of Essex, are now operated by First Essex. Journeys on route 7 operated by Arriva Herts & Essex are unaffected.

https://bustimes.org/services/63-the-weir-police-lodge-via-barling-rochford

Routes 21, 26, 27, and 28 had minor changes to bus operator tags ("First in Essex" to "First Essex").

(also https://bustimes.org/services/21-central-basildon-vange-pitsea-north-benfleet#map, but it doesn't appear that NIBS have bothered to update the routing, as it still shows buses not taking the slip road at Basildon Hospital roundabout on Nethermayne)

Sorry. Should clarify that these roads are in Eastwood (within the changeset area), and not the areas mentioned on the shipping forecast.
