A yojana according to many scripture interpreters measures 8 miles = approx. 15 km approx.
Rama Setu, the bridge built by Rama according to Valmiki Ramayana was 10 yojana width i.e. 160 km. wide.
Length was 100 yojanas = 1600 km.

Working fast, the Vaanaras, on the fifth day completed 23 yojanas of the bridge upto the other sea shore.
THIS BLOGGER'S OBSERVATIONS
To build a bridge across the River Godavari which is about 3 km. long and about 80 ft. wide, we take about four/five years, using modern technology. Then what should be the time taken to bridge of 160 km. width and 1600 km. length (Not 35 km. long Adam's bridge between India and Sri Lanka), using just hands?
In our blind faith towards our scriptures, we should not forget practicabilities.

Research Forum Meeting held on Sunday, the 4th November, 2007 at
1A2 Dolphins Apts, Beside Taj Residency, Visakhapatnam-530002, India.
According to this blog:
Prof E.C. La Fond heading the India Ocean Bed Mapping Project of
the United Nations worked as Professor and Founder of the Department of
Oceanography at Andhra University. He was on deputation from the
Scripp's Institute of Oceanography, Lajolla, Sandiego, California, .U.S.A.
Which is the world’s greatest Oceanographic Institution? He mapped the
entire Indian Ocean Bed during 1950-1960 (about) in a special Research
ship, in which many A.U.Departments participated. In 1980-81 he was
invited for a special lecture at the Andhra University and was questioned
after the lecture about the Adam's Bridge- Ramasethu.
He stated, that “The survey revealed that the Bridge was made of
Sand and Big Rocks and rises vertically from the Ocean Bed to the surface.
He said it was built since time immemorial and it was definitely a human
Construction and not a natural formation, either Volcanism or other
Geological Processes as sand and independent rocks as found do not come
together by natural Geological Processes." The Rocks seem to have been
taken from surrounding mountains on the Indian side and the sand from
The Rameswaram Sea shores. There are pillars at regular intervals to support
the bridge as seen in the map (Oxford Atlas).
