The two maps below show road access to a city hospital in 2007 and in 2010.
The two maps display how road access to a city hospital had changed by 2010 compared with 2007.
Overall, there had not been many changes made, except two new roundabouts, a new car park, and the replacement of the bus stops by a bus station.
Surrounding the hospital was Ring Road, which was connected to City Road by Hospital Road. By 2010, two roundabouts had been added, at the junctions of Hospital Road with Ring Road and with City Road respectively.
There was a car park for staff and the public on the southeast side of Ring Road in 2007. However, by 2010, it had become a staff-only car park, and a new public one had been built on the east side of this road.
The bus stops at two sides of Hospital Road were replaced by a large bus station, which had direct access to the two roundabouts. (150 Words)
Ring Road or ring road
For the purposes of this diagram, I would assume that the streets are literally named “Ring Road”, “Hospital Road”, “City Road”, etc. That is to say, These are proper nouns. Proper nouns need to be capitalized and shouldn’t be used with articles. So, it should be “Ring Road”, not “the Ring Road”.
How to Paraphrase the Question Statement
The key term “road access” has no good synonyms, so don’t try to change it. Instead, we can use a completely different construction.
The original uses a noun phrase.
We can instead use a “how” clause.
When describing the changes, I used the past perfect instead of the past simple. This is because all we have is two maps, one from 2007 and one from 2010, and at some time in the intervening period, the layout changed. It could have happened in late 2007, in 2008 or 2009, or in early 2010. If we say “in 2010 the car park became staff-only”, it means the change happened in 2010. That’s why I used the past perfect with ‘by 2010’: by 2010 the car park had become staff-only.
