Buses approaching Preston from Fishergate will be diverted next week because of the fracking hearings at County Hall.
From Tuesday, the city-bound bus lane on Fishergate will be closed, with all services heading towards Preston from Leyland, Penwortham, Riversway, and the Portway Park and Ride, being diverted along Bow Lane and onto Ringway.
The diversion will be in place from 7am on Tuesday June 23 to 7pm on Friday June 26.
In addition, the bus stop on Bow Lane will be used only for passengers who are getting off the bus, and the bus stop on Fishergate opposite the railway station will be out of use with passengers who want to travel towards the bus station being directed to alternative stops further down Fishergate Hill or on Ringway.
A Lancashire County Council spokesman said large numbers of people are expected to gather outside County Hall on Fishergate during the meetings and the bus lane closure is needed as part of a plan to safely manage the meetings. A petition is due to be handed over ahead of the first meeting on Tuesday morning.
