A1 Split Access Works Continue Into June: What Drivers Need to Know
Travelers heading to Split by car this spring have one practical detail to keep in mind before they leave: roadworks on the A1 are still affecting traffic between the Bisko and Split junctions in the direction of Zagreb, and that matters if your trip depends on a clean drive into or out of central Dalmatia.
If Split is your main base, our Split destination overview and Omiš guide help place this traffic update into a broader trip plan.
According to the Croatian Automobile Club (HAK), traffic remains closed between the Bisko and Split junctions in the Zagreb-bound direction until 12 June, with a detour via the Bisko exit, DC220, county roads, DC1 and Dugopolje/Split. HAK also says drivers cannot enter the A1 at the Bisko junction in the Zagreb direction during the works, while entry remains possible at Dugopolje.

For tourists, this is not dramatic news, just useful news. If you are collecting a rental car in Split, staying on the inland side of central Dalmatia, or planning to drive north after a couple of days on the coast, this is exactly the kind of update that can quietly cost you time if you miss it.
What is happening near Split
The key issue is simple. On the A1 Zagreb–Ploče–Karamatići motorway, HAK says traffic remains closed between the Bisko and Split junctions in the direction of Zagreb until 12 June. The official detour runs from the Bisko exit onto DC220, then along county roads and DC1 toward Dugopolje/Split.
That means travelers leaving the Split area for Zagreb, Zadar or anywhere else to the north should not assume the usual route will work in the usual way. If your map app has not updated properly, or if you are relying on quick verbal directions from a hotel desk, you could lose time around the junctions for no good reason.
This matters most for people staying in places that naturally feed into the Split–Dugopolje–Bisko corridor: Split itself, the inland edge of central Dalmatia and parts of the Cetina hinterland. The point is planning, not panic.
Solin–Klis is another point to watch
HAK is also reporting one-lane traffic in each direction on the DC1 Solin–Klis route because of roadworks between the Mravince and Klis Grlo tunnels, with the restriction in place until 1 May.
That matters because Solin and Klis sit on one of the most important practical approaches to Split and its hinterland. If you are linking city time in Split with airport transfers, inland stops or a drive toward Omiš, Imotski or the wider Dalmatian interior, even a moderate slowdown there can alter the day more than visitors expect.
In plain English, central Dalmatia is fully open, but some of the key road approaches are not moving as cleanly as they do in an ideal week.
Who should pay attention
This update matters most if you are:
collecting or returning a rental car in the Split area;
driving north after a coastal stay;
combining Split with inland central Dalmatia;
trying to connect a drive with a flight, ferry or fixed hotel arrival.
If you are visiting without a car, this may change nothing for you. If you are driving, it should change how casually you plan departure times.
If this is part of a broader Croatia trip, our first-time Croatia practical guide helps with the planning details that often matter more than people expect on transfer days.
The practical takeaway
First, check HAK on the day you travel, not just when you first sketch out the route. It remains the strongest live source for Croatian road conditions.
Second, if you are leaving Split toward Zagreb or the north, assume the Bisko-to-Zagreb pattern may be slower or less direct than usual and plan around Dugopolje access where relevant.
Third, if your travel day links too many moving parts, trim the plan if you can. Dalmatia rewards slower travel anyway. Better to arrive twenty minutes early for coffee than to watch a timetable fall apart because one junction was more awkward than expected.
Why this is worth mentioning
This is the kind of road story that rarely feels glamorous and still matters more than louder travel headlines. Croatia often feels easy once you are on the coast. The friction usually appears in transitions: airport to town, coast to inland, one base to the next. That is why route updates like this deserve a place in traveler planning.
Nothing here suggests anyone should avoid Split or central Dalmatia. The region remains easy to visit. The smarter takeaway is simply to check the live road picture and give yourself more room than usual around the Split–Dugopolje–Bisko axis.

No. Split remains easy to reach, but some approaches and northbound onward movements need a little more planning than usual.
How long do the A1 works near Bisko and Split last?
HAK says traffic remains closed between the Bisko and Split junctions in the Zagreb-bound direction until 12 June.
Is the Solin–Klis route fully closed?
No. HAK reports one-lane traffic in each direction due to roadworks, not a full closure.
