Imotski, Vrgorac and the D76: the Sveti Ilija tunnel behind Biokovo

Between the coast and the motorway stands a mountain. The D76 goes through it, and that single tunnel changes how every recovery and every inspection on this corridor is organised.

What defines this route

The D76 links the Makarska riviera with the inland Zagora and continues to the Bosnian border. Its central feature is the Sveti Ilija tunnel through Biokovo, between Bast above Baška Voda on the coastal side and Rastovac near Zagvozd inland. Before it opened, the journey meant a long climb over the ridge.

At Zagvozd the D76 meets the D62, which runs west to Šestanovac and east to Vrgorac, and the A1 junction sits at the same place. Further east the D512 links Makarska directly to the A1 at Ravča. It is a small triangle of roads joining two very different worlds.

The contrast is the point. On the coast the traffic is holiday traffic, dense and slow; ten minutes inland it is agricultural, sparse and fast. Drivers change behaviour at the tunnel portal without noticing, and so do the conditions.

Imotski and Vrgorac are the working towns of the inland side, and that is where the workshops, recovery yards and police stations are. For anything happening on the riviera above Baška Voda, the practical centre of gravity may be on the far side of the mountain.

What damage looks like here

Tunnel approaches and portals. Speed drops, light changes abruptly, and the queue at the coastal end builds in season. Rear-end impacts here are the standard case, usually at low speed with sensors and towbars taking the damage.

Sideswipes on the inland sections. Narrow carriageway, stone walls at the edge, agricultural vehicles and no shoulder to pull onto. The mark runs lengthways over several panels.

Descents towards the coast. The drop from the inland plateau to the riviera is steep and continuous. Brake fade, overheating and damage after a low-speed run-on at a bend are all more common here than the traffic volume suggests.

Livestock and game on the Zagora sections. Sheep and goats graze unfenced near Vrgorac and Imotski. The bodywork damage is modest and the bill sits in the cooling pack and the sensors.

What counts on the day

Fix where you are with something a stranger can find: the tunnel portal and which side of it, the nearest settlement, or the distance from the Zagvozd junction. The two sides of Biokovo look nothing alike, and saying which one you are on settles half the question.

• Photograph the final position of every vehicle before anything is moved
• Record the carriageway, the wall or drop, and the light conditions at the portal
• For animal contact, capture the road, the surroundings and the height of the damage
• After a long descent, photograph the wheels and brakes before the car cools
• Note which side of the tunnel you are on — it decides where recovery goes

Recovery goes to Imotski, Vrgorac, Makarska or Split depending on the section and on which side of the tunnel the vehicle stopped. Ask at the scene where it is taken; here the destination can be forty minutes and one mountain from where you expect.

The inspection comes before any repair. MOTOEXPERT records the damage where the vehicle stands, on either side of Biokovo. We work exclusively as independent technical experts; liability and policy cover belong with the insurer and a recommended lawyer.

Frequently asked questions

The damage happened just before the tunnel. Does the inspection have to be there?

No. It takes place wherever the vehicle stands after recovery, which on this corridor may be on the far side of the mountain. What matters is that the scene was documented on the day: light at a portal and the state of the queue cannot be reconstructed afterwards.

My car was recovered to Imotski but I am staying in Makarska. Is that a problem?

An inconvenience rather than a problem, and a common one here. The inspection is arranged where the vehicle is, not where you are, and the tunnel puts the two points about half an hour apart. Keep the recovery paperwork; it establishes where the car went and when.

The brakes faded on the descent and I ran into the car in front. What is documented?

Both, separately, because they are separate findings. The contact damage is recorded in the usual way. The state of the brakes, discs and tyres is recorded as its own item, ideally before the vehicle cools, since heat marks fade. Whether the two are connected is answered from the vehicle.
