A6 highway (Lithuania)
The speed limit for most of the length of A6 is default 90 km/h (outside city limits). The section from Kaunas to Jonava has been upgraded to a dual carriageway with at-grade junctions and traffic-lights. The remaining sections are roads with one lane in each direction, leading through towns like Ukmergė, Utena and Zarasai.
M50 motorway (Ireland)
The original speed limit on the M50 was 70 mph (112 km/h). The Southern Cross Route from J12-J13 was given a lower limit of 60 mph (96 km/h), due to its more undulating, twisting route. The route from J3-J13 was changed to 100 km/h after the Republic of Ireland's speed limits became metric in 2005, while the Southeastern Motorway section (J13-J17) became 120 km/h. The Airport Motorway-Port Tunnel section of the route from J1-J3 has a speed limit of 80 km/h due to the closely packed junctions and heavy volume of weaving traffic.
