An alternate solution - rebuild Belle Vue Junction

The design here proves in principle that by utilising the area of the swimming pool (in part: see area bounded by blue dashed line) Belle Vue Park can be redesigned to allow a turning off the junction up Newton Road.

This has three effects:

1. It counteracts the effects of any blockage to the one way system on Gainsborough Street, Gainsborough Road and Girling Street as traffic that would otherwise be trapped in the town centre could use Newton Road and then access otherwise inaccessible parts of the town or the A131/A134 to BSE and Colchester. This alleviates any need to use New Street and North Street for a diversion. Additionally Great Eastern Street. Friars Street and Church Street can be used for all but HGVs to access the A131 to/from Halstead and Braintree. 
2. It removes any need for junction improvements at Ingrams Well Road/Newton Road. Hence preserving the quiet nature of  Ingrams Well Road (it will no longer be a ratrun) and enabling a safe pedestrian route into the Park from Cornard Road.
3. It takes pressure off the east side of King Street and enables East Street to be made one way, thus alleviating traffic congestion on East Street and enabling safe cycling infrastructure. SCC have such a plan for East Street and I have discussed this with various SCC Highways people at points over the last 10 years. It would be essential to enable any cycle route from Chilton Woods to be safe and link to the Town Centre.
