Major investment: The most expensive motorway in Hungary to be built soon
A major new motorway in Hungary is on the horizon, and it’s set to be the country’s most ambitious road project yet. The M100, announced by Transport Minister János Lázár, will stretch over 32 kilometres and connect the Esztergom region to the M1, opening up a vital link to both Budapest and international routes.
New motorway in Hungary announced
As VG reports, Hungary is gearing up to build its most expensive and complex motorway, the M100. The announcement came from Minister of Construction and Transport János Lázár during a public meeting in Szentendre this May.
Stretching over 32.3 kilometres, the new motorway in Hungary will link the Esztergom region to the M1 motorway, a major route connecting Hungary to the broader international transport network. With ten tunnels and several valley bridges planned, the project is expected to cost around HUF 500 billion (EUR 1.2 billion), reflecting its scale and technical difficulty.
Boosting regional connectivity
The M100 isn’t the only transport upgrade on the agenda. Minister Lázár also confirmed plans to renovate the Szentendre HÉV line and finally move forward with the long-delayed reconstruction of Road 11. These developments are part of a wider national strategy to improve mobility and ease congestion. The M100, however, is the centrepiece. Construction is expected to start in 2026, at the close of the current government’s term. Once complete, this motorway in Hungary will dramatically improve access to the M1 and better connect key regions to the capital.
The M10 is also coming
Alongside the M100, preparations for another crucial route, the M10, are also underway. This motorway will connect Esztergom to Budapest via Solymár, further relieving traffic pressure in the area. The M10 and M100 together form a vital part of Hungary’s future road network, aimed at reducing traffic on overcrowded routes like the existing Route 10, notorious for morning tailbacks. Residents of towns such as Piliscsaba and Pilisjászfalu will finally see relief as heavy freight and commuter traffic are redirected onto purpose-built infrastructure.
The most expensive motorway
Plans for the M100 include a staggering 52 bridges, ten tunnels, multiple junctions, and dedicated rest and weighing stations. Noise barriers will also be constructed to protect nearby communities. Originally estimated at HUF 350 billion (EUR 867 million), costs have risen due to the increased technical demands.
