The court also suggested that the concessionaire open the boom barriers for at least five minutes in case of congestion.
The police asked the concessionaire to install signages at the red line on both sides of the Sirhaul toll plaza so that the court order could be implemented easily.
Keeping in view the advent of fog, the police asked the firm to install LED reflectors along the expressway.
