A NEW road to a proposed Bognor Regis commercial site could cost up to £18m, a study has shown.
The highway infrastructure viability work into the north-south link from the intended Enterprise Bognor Regis site says the road makes financial sense.
It will link the business park on the former Lec airfield site with the new relief road to the north and the existing A259 roundabout at the Inspire Felpham Leisure Centre to the south.
Consultants Systra said in the report: “The proposed link road will provide necessary highway infrastructure to enable the development of sites within the Enterprise Bognor Regis masterplan, particularly the former Lec airfield site.
“As such, its main function will be to act as a primary distributor for local development traffic, enabling access to development.” Systra considered three options for the link road:
n Option one: connects directly with the relief road to the north and the A259 to the south and stays east of the railway line;
n Option two: The same at the southern end but connects into the A259/relief road junction via a bridge over the railway line and Oldlands Farm; and
n Option three: also goes over the railway line and connects to the relief road between its junction and the A29 and the railway line.
The last option was soon ruled out because it involves the same work as option one but an extra bridge over the railway line.
Both options one and two were feasible but number two would cost about £17.9m compared to £11.3m for number one.
Option one was also marginally more favourable because it would have less impact on existing traffic.
Systra’s report says two-way traffic flows on the single-carriageway road are forecast to range between 308 and 726 vehicles during a typical weekday peak period in 2031.
As the road would travel through an area at significant risk of flooding, the report says its vertical alignment would likely be around one metre above the existing ground level, except where the route crosses the Lidsey Rife where the road will need to rise to around five metres above ground level.
