Along this section, the canal is hemmed in by dense hedgerows as far as Crossover Bridge, beyond which it enters more open country as it approaches the junction with the non-navigable Longford Branch and continues on to the 43rd Lock, near Killashee village. Shortly after the 44th Lock the canal enters Begnagh Bog. Beside the original Begnagh Bridge is a lifting bridge carrying the Killashee to Cloondara road across the canal. The bridge opens automatically and should be approached slowly to allow time for the road barriers to be lowered and the bridge to lift before the green light appears.
Approximately 1.5 km beyond Begnagh Bridge the Bord na Möna light-railway crosses the canal via another lifting bridge (non-automatic) which is normally kept in the open position. The second Bord na Möna bridge alongside is a high- level machinery crossing. After passing through the 45th Lock at Rinnmount the canal shortly enters the terminus at Richmond Harbour.
The 46th Lock, at the far end of the harbour, leads into the Camlin River which connects with the River Shannon in Lough Forbes or, by passing down a short length of canal and through the old Shannon Navigation Lock, below the weir at Tarmonbarry.
