"To try to control boat passages through locks in support of the government’s instructions, Tewkesbury, Strensham, Pershore, Wyre, Evesham and Trinity locks are closed to normal traffic, however they can be booked for essential passages. Boats should book a passage 24 hours in advance by ringing 0300 111 2010. A team will then be sent to the relevant site to open the lock at an agreed time (Monday to Friday between 9.00am and 4.00pm)."
