The Finn River passes under numerous bridges on its way to
Upper Lough Erne. Most of these bridges were built in the mid- to late eighteenth century or sometime in the nineteenth century, and almost all of them are built of stone. The following bridges are listed in order, going from the river's source to the river's mouth. and Derryvollan (also spelled as Derryvullan) Bridge, located a few miles north-north-east of Roslea, which carries the Deerpark Road across the Finn from County Fermanagh into County Monaghan. Derryvollan Bridge, which is also known as Flynn's Bridge, is located a short distance south-west of
Knockatallon, a
hamlet in the north-west of County Monaghan. Corragunt Bridge, which does not cross the Finn, is just north-west of Derryvollan Bridge. Lisnawesnagh Bridge, which is constructed of stone, is located just north-east of Roslea and also carries the Deerpark Road across the Finn. There are three bridges on the edge of Roslea itself, a village surrounded on three sides by the Finn. These Roslea bridges, all of which are built of stone, include the bridge on the southern edge of Roslea which carries the Mullanahinch Road (the sideroad to
Clones) across the Finn River.
Roslea to Cumber Bridge New Bridge, a small concrete bridge built in the twentieth century, is located just over a mile south-south-west of Roslea. This bridge is on the south-western edge of Spring Grove Forest and carries the Clogh Road across the Finn. This 'lane' runs up over the
drumlins overlooking the Finn River, running from New Bridge to a junction on the sideroad between Clogh and Stonebridge; thus, 'the Gorry Lane' crosses from County Fermanagh into County Monaghan. The 'lane' runs just to the west and south of Rathkeevan Lough. The Finn also flows under an
aqueduct just south-east of Stonebridge. This aqueduct, which crosses from the
townland of Conaghy to the townland of Gransha Beg, is built of stone and carries the now largely derelict
Ulster Canal across the river. Part of the aqueduct is now used as a road bridge, carrying a narrow sideroad across the Finn. It then flows under Analore Bridge, parts of which date from 1720. This bridge is located in the hamlet of Analore, between Clones and
Newbliss, and carries the
R183 across the river. The Finn flows under the now derelict Annaghkilly Railway Bridge, located close to the former Ballynure
Demesne, immediately south of Analore. This bridge was built in the late 1850s and is constructed of stone. The river flows under Scarvy Bridge, a
humpback bridge constructed 1820 and built of stone. It then flows under Cumber Bridge, which was constructed 1800 and is also built of stone. Annies Bridge is almost 2.8 miles (around 4.5 kilometres) south-south-west of Clones. It formerly carried the
Clones and Cavan Extension Railway (the main railway line from Clones to
Cavan Town) across the river. This railway line closed in the late 1950s. . The Finn River can be seen flowing under the ruined bridge, with
County Fermanagh on the left and
County Monaghan on the right. Parts of the river now form a tiny part of the
external border of the European Union. Gortnacarrow Bridge, which was built in the mid-eighteenth century, carries the Cavan Road (also known as 'the Concession Road', All these bridges are built of stone. There are two bridges at Derrykerrib, both of which are modern, concrete structures, located slightly to the north of the Finn River's mouth. These bridges are right beside each other, the older of the two dating from the late twentieth century, while the newer bridge was completed in 2018. These bridges carry the Derrykerrib Road from Edergool, a townland on the Fermanagh 'mainland', across a narrow channel of Upper Lough Erne and onto Derrykerrib, a townland that was formerly an island. A new navigation channel was also cut in 2017 and 2018, when the new Derrykerrib Bridge was being built. The new bridge spans this channel, which was cut on the Derrykerrib shore of Upper Lough Erne. This new channel allows boats to sail, via the Finn River, as far as the jetty at
Castle Saunderson in County Cavan. The entrance to the now derelict
Ulster Canal is beside the Derrykerrib Bridges, being just north of them. == Other nearby bridges ==
