Sir Ronald Thomson, the British representative in Persia, having at the same time induced the shah to consider the advantages to Persia of opening the Karun River and connecting it with Teheran by a carriageable road, a small river steamer for controlling the shipping on the Karun was ordered as well, and the construction of the road was decided upon.
The scheme of opening the Karun and of constructing a carriageable road from Ahvaz to Teheranwas also abandoned.
In 1890 the scheme of a carriageable road from Teheran to Ahvaz was taken up again; the Imperial Bank of Persia obtained a concession, and work of construction was begun in the same year, and continued until 1893.
