[6] From the eastern end of the Greenway the Prittle Brook flows under Victoria Avenue (A127), through Priory Park and north, past London Southend Airport to Rochford and eventually joins with an arm of the River Roach (Fleethall Creek) at Sutton Bridge (51°34'27"N 0°42'59"E).

[8] A 5.7 km pathway (officially designated the "Prittle Brook Greenway" in 2010) enables walkers and cyclists to follow the section of the Brook from Belfairs, past Southend University Hospital to Roots Hall, effectively providing a route from Leigh into Southend which avoids the main roads.

This part of the Brook's route has been urbanised since the 1930s, and the banks have been concreted east of the Belfairs Wood area.

[10] The brook was subsequently culverted and provided with concrete embankments west of Daws Heath Road.

The Prittlewell Brook [sic] Monitoring Station is located in Belfairs Park (51°33'10.9"N 0°38'28.0"E); it comprises a concrete flume and equipment  cabinet.
