Projected traffic flows for southern access options

We have undertaken a traffic modelling exercise to assess the impact of each option. On the wider highway network, the impact of each access option is very similar and results in some increases in traffic flows, as would be expected for a major site development. The impact of the southern access option is slightly less as it enables greater spread of trips around the city. An indication of the traffic impacts on the local highway network is shown on the diagrams for the Southern option and Western options.

An access to the west also provides an alternative route to Leeman Road, greatly reducing trips on residential streets to the north of the site. There are moderate increases in traffic on Water End and the A19 as a result of new development trips and greater increases in trips on Poppleton Road, with existing trips diverting away from Water End.

The southern access option provides a new access to the south / west of the rail lines. The traffic flows are predicted to have a greater increase on the A59 Poppleton Road, close to the proposed access, but slightly reduce trips on some routes as existing trips divert away from the A59. There are also moderate increases in traffic on Water End and the A19.

For all access options, the modelling predicts slight reductions in trips on some city centre routes because additional routes are available through the site – for example, on the A1036 and Queen Street as indicated by the blue lines to the east of the station.

Commentary

Construction

Western option 01 will require the construction of a new bridge at Water End over the East Coast Main Line and further works to the existing bridge at Water End to create a right turn lane into the site.

Western option 02 would not require changes to the existing bridge over the East Coast Main Line at Water End.

The road alignment passes across Flood Zone 2 and Flood Zone 3.

The Southern option would consist of a single span bridge.

It will require the relocation of an existing electricity sub-station.

Townscape

A tied arch bridge would be required for Western option 01 due to the required span over the East Coast Main Line. This may increase the townscape impact compared to Western option 02 and the Southern option.

The Leeman Road Millennium Green Mosaic may be affected by the Western option 01.

There may be some visibility of the new access route from long
distance views towards the Minster depending on the height of any required bridge structures.

The Leeman Road Millennium Green Mosaic may be affected by the Western option 02.
