7th Ring Road (Beijing)
I saw a snippet that work is commencing on Beijing's 7th Ring Road and is scheduled to open within two years. The Beijing section will cover 90kms and it is intended to link is some sprawling communities in Hebei province, that will total 940kms.
The amazing fact is that, the last I was in UK it could take 2 years to repair one highway section never mind build the whole thing!
Downside is that you could expect your rental prices to increase in line with improved commutability , the good side is that the property owners can expect their property values to increase :P
