Eko Bridge Definitives
Original photogravure printing and corrected lithographic printing of the one naira definitives of 1973-1974.
Eko Bridge, the western-most of three bridges connecting Lagos island with the mainland, spans 430 metres connecting Ijora in the Apongbon area. The bridge and a landward extention were built by Julius Berger Construction of Nigeria over a decade beginning in 1965. The bridge was featured on the one naira denomination of the Nigerian definitive issues of 1973 and 1974. On the first photogravure printing issued on January 6, 1973 the traffic was shown driving on the left. This would have been the case before April 4, 1972, but from that date Nigeria had changed from right-hand drive inherited from colonial times to left-hand drive consistent with Nigeria's neighbours. This was corrected on the subsequent lithographic printing of the stamp.
On June 23, 1972 Nigeria issued a set of four stamps commemorating
the introduction of right hand driving in Nigeria on April 2, 1972.
