 According to an Environmental Statement issued by BAA, Airtrack would have had a slight impact on eight crossings, with barrier closure times increasing by no more than 13%; three crossings would have been moderately affected, with closure time increases of between 13% and 25%; and four crossings would have been "severely" affected, with barrier downtime increasing by between 25% and 36%.Wokingham Borough Council objected to BAA's plans on the grounds that no proper impact assessment had been carried out on level crossing dwell times.BAA investigated the possibility of constructing new road bridges or tunnels to mitigate problems with level crossings.
