10. A127 Ardleigh Green Bridge replacement - update • Bryant Avenue exit onto A127 • Two periods of closure: • Early 2016 for about four weeks • Summer 2016 for about nine months

11. A127 Ardleigh Green Bridge replacement - update • Reasons for closing Bryant Ave exit: • To provide sufficient space for the working area near the bridge. • A protective barrier needs to be in place on the bridge to stop vehicles driving onto the railway and into the works site. • The new bridge will be higher than the current bridge. Raising the road surface requires steps to be in place at times during the works, which are unsuitable for traffic. • Utilities (water, gas etc.) need to be diverted below and near the Bryant Avenue traffic island (requiring a shorter closure of Bryant Avenue in early 2016).
