It took me 6 weeks to design and 6 weeks to build the arch that is pictured in your article on Uthant (Belmont) island. It was erected on August 18 I believe the year was 1982. I signed the Southern concrete footing Eastern side, under the name "Himangshu" with the date. The Arch was designed as 4 interconnected catenaries 19.75' tall and 50' long and so matches this design element in the bridges visible north and south from it.
