Loddon Viaduct contraflow starts

Loddon Viaduct contraflow starts

21 July 2016

The contraflow on the northern carriageway of the A3290/A329M Loddon Viaduct is due to start after evening rush hour on 22 July, and could last up to six weeks.


Throughout this time the southern carriageway will be closed, but the contraflow on the northern side will keep traffic on the viaduct moving in both directions 24/7 – one lane westbound towards Reading and another eastbound for Bracknell.


However the westbound slip road onto the viaduct from Winnersh Triangle (toward Reading) will also be closed because it would normally funnel onto the southern carriageway. The diversion for this slip road will be west along A329 Wokingham Road, north along Church Road, north along Pitts Lane and southwest along A4 London Road.


Eastbound access onto the viaduct toward Bracknell, and the M4 along the slip road from Bader Way, will merge via a single lane with the contraflow traffic already on the viaduct, which may cause delays at peak times.


Westbound motorists from Bracknell or M4 wishing to exit at Winnersh Triangle will have a dedicated lane in advance of the contraflow to exit.


Temporary speed limits of 30 mph and 50 mph will be in force and an emergency breakdown service available within the contraflow and lane restriction sections.


This £1.1million Wokingham Borough Council scheme is a major project to replace the old and noisy bridge joints on the viaduct, install new permanent safety barriers, redo waterproofing, and resurface the carriageway.


The borough council repaired and upgraded the northern (eastbound towards Bracknell) carriageway of the viaduct two summers ago. Like then, the main bulk of the work is being carried out during the school holidays when roads are traditionally quieter.


But if you use this route please still allow yourself more time, or preferably seek alternative routes. Remember the local road network will be busier because of this scheme.

Regular posts will be put on the council's Facebook and Twitter profiles and residents can also sign up to the council’s roadworks text and email alerts.
