National Route 840 (N840) is a major secondary route that forms part of the Philippine highway network. It serves a diversion road for both Cebu North Road and Natalio Bacalso Avenue/Cebu South Road (both N8), from Liloan to Talisay. ^{[1] [2] [3] [4]}

Route description

Consolacion–Tayud–Liloan Road

N840 begins in a Y-junction with Cebu North Road (N8) as Consolacion–Tayud–Road in Liloan. It traverses Consolacion, which shares a barangay with the former in this road called Tayud. The road meets its end in Cansaga Bay Bridge.

Cansaga Bay Bridge

This separate portion that carries N840 is called the Cansaga Bay Bridge, connecting Mandaue and Consolacion.

Mayor Demetrio M. Cortes Avenue

N840 starts as Mayor Demetrio M. Cortes Avenue right after passing the Cansaga Bay Bridge. It intersects with United Nations Avenue (N841). The short segment ends in an intersection with A.C. Cortes Avenue (N82)

Ouano Avenue

After its intersection with A.C. Cortes Avenue (N82), N840 continues as Ouano Avenue. After passing the Ouano Bridge, the road takes a sharp turn. It traverses through the southern part of Mandaue, including the North Reclamation Area, being beside major buildings such as Bai Hotel Cebu and Cebu International Convention Center.

Second Avenue

N840 continues as Second Avenue right after leaving Mandaue and Ouano Avenue starting from the eponymous bridge. After the route reaches the MacArthur–Padilla Bridge, the Second Avenue section ends.

Sergio Osmeña Avenue

N840's continuation, the Sergio Osmeña Avenue, continues after the MacArthur–Padilla Bridge and Second Avenue. It continues as a straight six-land divided road until it ends in a junction with Legazpi Highway.

Cebu South Coastal Road

The four inner lanes from Sergio Osmeña Avenue continue in a tunnel and become the Cebu South Coastal Road. Once it exits the tunnel, it is carried by the Viaduct Bridge. Before the bridge ends, the Cebu–Cordova Link Expressway forms. ^[5] Around this point, the kilometer count reverses due to it being south of the kilometer zero, making it parallel with Natalio Bacalso Avenue. After exiting the bridge, Route 840 enters and serves the general area of the South Road Properties, with it being adjacent to significant business centers including the SM Seaside City. The road enters Talisay where after a sharp turn, N840 ends in the Natalio Bacalso Avenue junction.
