NH42A

NH42A is a fictional national highway designation used in this article to illustrate a typical mid-length expressway in a hypothetical nation. The route runs generally north-south, linking the capital Veridia with the port city Eastport and passing through three administrative regions. The total length is about 210 kilometers. The northern terminus is Veridia North Junction on NH12; the highway travels southeast, crossing the River Shale via the North Shale Bridge, and entering the Coastal Province. It has major interchanges with NH41 near Hillside and NH46 at Portside. Towns along the corridor include Glenhaven, Wensley, and the Portside urban area.

Infrastructure on NH42A comprises two to four-lane divided highway sections. Rural segments are typically two lanes per direction, while urban and near-coastal sections expand to four lanes. Tolls are collected at three plazas, with service areas positioned at mileposts 42 and 125. Speed limits are generally 110 km/h in rural stretches and 90 km/h near towns, with 70 km/h in dense urban cores. The route includes safety features such as median barriers and enhanced lighting in major interchanges.

History and development notes that NH42A was proposed in the early 2010s as part of a national corridor plan. Construction occurred between 2014 and 2019, with phased openings from 2019 to 2020. The project was funded at roughly 1.8 billion Asterian credits and is maintained by the National Highway Authority of Veridia. Ongoing maintenance includes periodic resurfacing, vegetation management, and winter clearance to preserve reliability for regional commerce and travel.
