R4 expressway (Košice – Prešov – Svidník – Polish border)

Full profile from the start, category R 24,5/120 (R 24,5/100 between Kechnec and the border). 16 bridges and 2 interchanges, among them the 530 m bridge over the broad-gauge railway. sk.wikipedia gives construction costs of EUR 78 million against an initial state expert estimate of EUR 117 million; the VAT basis and price year are not stated, so neither is recorded as a money field. The drawn line starts at the Košice, Juh interchange and ends at the border (14.1 km, about 1% under the recorded length). The section east of Košice, Juh up to Košické Oľšany shares the route of the R2 and is not part of this lot.

Built as a single carriageway (half profile, category R 11,5/100 or R 22,5/100) with 9 bridges, the Svidník, Juh interchange and an at-grade connection at Svidník, Sever. The left half is not scheduled before 2028 per sk.wikipedia. The drawn line is 4.4 km, about 4% under the recorded length.
