Bratislava to Budapest by car: via Rajka or through Slovakia

From Bratislava hlavná stanica to Budapest-Keleti pályaudvar there are two main routes: south on the D2 to Rajka, or east through Slovakia to Komárno. On OpenStreetMap routing the Komárno route is about 8 km shorter but roughly 25 minutes slower without traffic, so apps can swap between them. To check today's live times for this exact route, compare this route on Mapssy, then open your driving app to see which crossing it picked.

The route options at a glance

Via Rajka: the D2, M15 and M1

The D2 crosses the Danube on the Lafranconi bridge and runs south past Petržalka. It is free inside the city, as is the whole D4 bypass except about 2 km at the Austrian border (eznamka.sk, July 2026); a vignette is needed only for the last 9 km, from the D2/D4 junction at Jarovce to Čunovo.

In Hungary the M15 runs about 14 km to the M1 near Mosonmagyaróvár, and the M1 roughly 160 km on to Budapest. The last 78 km of that, from the Concó rest area to the M0, are inside the widening works described below, where lower limits apply.

To skip the Slovak vignette, the old I/2 runs parallel through Rusovce to its own crossing at Rajka, continuing as Hungarian road 150.

The M1 works and your choice of route

MKIF, the M1's operator, is adding a third lane each way between the M0 junction (km 16) and the Concó rest area near Bábolna (km 94), targeting 31 August 2028 and 31 August 2029 for the two phases. From late September 2026 both directions between the M0 and Tatabánya move onto one carriageway in stages: 90 km/h on open stretches, 70 km/h near junctions.

Every motorway route from Bratislava passes through the works; even the Komárom junction (km 85) lies inside them. Only the Štúrovo–Esztergom route avoids the M1. Closures are on MKIF's M1 site, and the autumn layout is in our Vienna to Budapest guide. MKIF's M1 pages do not mention M15 works; check Útinform before you go.

Through Slovakia: the R7 and Komárno

The R7 expressway runs south-east from Bratislava to Holice; the 25 km from the D4/R7 junction to Holice need a vignette. Road I/63 then passes Dunajská Streda on a bypass and reaches Komárno after roughly 60 km of two-lane road through villages (90 km/h outside them); with Hungarian road 13 to the M1 it is about 70 km.

Komárno has two road bridges. The Monostor bridge, opened on 17 September 2020, lies about 3 km upstream of the older Elisabeth bridge (Alžbetin most) between the town centres, and road 13 leads from it to the M1 at the Komárom junction (km 85). Apps may instead use the Elisabeth bridge, about 2 km longer on OpenStreetMap routing.

It pays off when the D2, the Rajka crossing or the M1 west of Komárom is blocked; on a clear road the two-lane section makes it slower.

The Štúrovo variant stays on the I/63 to Štúrovo, crosses the Mária Valéria bridge (reopened in 2001) into central Esztergom and takes roads 117 and 10 to Budapest. At about 203 km it is no longer than the others, but with no Hungarian motorway and mostly two-lane road it is by far the slowest.

Vignettes for this route

Slovakia: buy on eznamka.sk, its app or an official point of sale it lists, such as a petrol station; avoid third-party resale sites. A 1-day vignette (€8.10 on 26 September 2026, valid until midnight on the chosen day) covers either the D2 to Čunovo or the R7 to Holice.

Hungary: buy the e-matrica before joining the M15 or M1. It is valid from purchase; the 60-minute window after entering is only for drivers who join by mistake. The daily vignette (5,550 Ft, 0:00–24:00 on the chosen day) is cheapest for a same-day return; otherwise the 10-day one (6,900 Ft) covers the trip back (2026 car prices, checked 26 September 2026). County vignettes are annual, at 7,190 Ft each; the Rajka route crosses four counties, the Komárno route three.

Regular drivers should consider the 2026 M1 regional e-vignette (15,000 Ft a year for a car), valid on every toll expressway in Győr-Moson-Sopron, Komárom-Esztergom, Fejér and Pest counties, the M15 included. Driving on a toll road with no valid e-matrica brings a 27,790 Ft surcharge (2026 rate) if paid within 60 days, or 95,730 Ft after that. Full price lists are in our vignette guide.

Borders: no checks unless you go through Austria

On 26 September 2026 the European Commission's list of border controls showed no checks by Slovakia or Hungary.

A line west to the Jarovce–Kittsee crossing and along Austria's A6 and A4 to Hegyeshalom needs a Slovak vignette for the 2 km D4 border section and an Austrian one (1-day €9.60 in 2026, digital only). Austria is also checking traffic at its Slovak and Hungarian borders until 15 March 2027; see border checks in 2026.

Why the apps may pick different routes

With Rajka and Komárno within about 8 km of each other, the choice rests on the speed each app expects: a queue at Čunovo, an M15 closure or slow traffic west of Komárom can tip one app towards Komárno. The general reasons are in why navigation apps show different arrival times.

• Traffic data. Each app has its own live sources; MKIF says it publishes M1 traffic information on its site, Útinform and Waze.
• Changing works. Layouts and limits in the works zone reach each app's map at different times.
• Settings. With tolls avoided, an app may use the I/2 at Rajka or the I/63 to Štúrovo.

How to see which route your app chose

• In the route overview, M15 or Rajka means the south route. R7 or 63 means Slovakia; then Komárom or Monostor means Komárno, Vámosszabadi or Győr means Medveďov, and Esztergom means Štúrovo. A6 or Hegyeshalom means Austria.
• Mapssy shows a measured distance only for Google Maps and TomTom (its web Waze and Apple figures are estimates). Around 204 km usually means Rajka and around 196 km Komárno, but tap Open in the app you will drive with to see its line.
• If the route looks odd, check whether avoiding tolls or motorways is switched on (app settings).

Arriving at Budapest-Keleti

Every route reaches Budapest on the Buda side: the M1 ends at Budaörsi út and the Štúrovo route comes in on road 10. Keleti is across the river at Baross tér, so apps also differ on the Danube bridge or the M0. Street parking has been paid by app, text or call since meters were withdrawn on 1 July 2026; zones and the Kelenföld P+R are in the Vienna to Budapest guide.
