This stamp sheet commemorates a project to "split" a section of the Algerian N-01 highway that runs north to south through the country (to me, splitting would imply separating traffic lanes, but perhaps this is something different). Looks like it was a fairly large project that included 35 bridges and 3 tunnels.
