Hit the switch on your right to open the gateway and proceed into the Lower Waterway. Turn around and head back across the bridge, then up the stairs.
Cross over the bridge and pick up the Sewer Keys from the wall. Turn left and use the T-Bar Valve Handle to open the gate at the end of the corridor. Now exit the room via the door to the south-east and move down the stairs. Near the Tram you will find a T-Bar Valve Handle. Cross over and turn left, towards the Tram. Exit the Monitor Room through the eastern door into the Treatment Pool Room and lower the bridge using the switch. Both Leon and Claire get to the Monitor Room following slightly different paths, but the route from here is the same for both. However, once you reach the Monitor Room in the Sewers, you can finally get back to the Special Weapon Case. And by the time you do, you can’t get back here. Sadly, you don’t have the key at this point. You first access the area by opening the secret passage in the Main Hall of the police station. The Special Weapon Case is in the Underground Stairs. On that note, make sure you keep the USB Dongle Key from the Police Station and take it with you on this journey. You should bear in mind that, while both the puzzle and its solution are found in the Police Station during the early stages of Resident Evil 2, you can’t solve it until much later.
