D54 in Zaton Obrovački D502 in Donji Karin D503 in Zapužane A1 in Benkovac interchange D27 is a state road connecting Gračac in the southern part of Lika, Croatia, to D8 state road via Benkovac.

[1] It also provides an alternative route to the sections of A1 motorway and the D8 state road that cross the Maslenica strait over the two Maslenica bridges, underneath the Velebit.

This is especially important when strong wind or storms (usually the bora) cause the A1 motorway section between Maslenica Bridge (A1) and Sveti Rok Tunnel to be closed for traffic for safety reasons.

[3] Traffic is regularly counted and reported by Hrvatske ceste, operator of the road.

[4] Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the road connects a number of summer resorts to Croatian motorway network.
