Banawali’s ‘acropolis’ and the ‘lower town’ give the acropolis an
        arch shaped assymmetrical form.
     •  Dholavira forms a category of its own because its open spaces and
        triple divisions between the lower town, middle town and the citadel
        have not yet been matched at any other settlement.
     •  There are some small but presumably urban settlements (e.g.
        Ahladino, Hulas), which have neither internal divisions, nor enclosing
        walls.
Relationship between Planning and Size
No direct relationship exists between the degree of planning of the Indus
cities and their size. The best example is the contrast between Lothal and
Mohenjodaro. Mohenjodaro is about 18 times the size of Lothal, but both
share similar features like burnt brick houses, regularly aligned streets, burnt
brick drains, etc. On the other hand, Kalibangan, which is more than twice
the size of Lothal, is much poorer in comparison. For Kalibangan suffers
from very limited use of burnt bricks, civic drainage and wells, among other
things. Therefore, mere size in the Indus context does not indicate whether
the site was rich or poor, properly planned or unplanned. Thus, on the whole,
the distinction between a village, a town and a city is to some extent, blurred
among the Harappan settlements.
Arrangement of Streets and Lanes
The main streets in each city were of considerable width. The north-south
First Street in the HR area at Mohenjodaro was 30–35 ft (9.14–10.66 m)
wide. Among the lesser ones, a width of around 13 ft (3.96 m) is supposed to
be common. But all the lanes were considerably narrower. At Mohenjodaro,
their width ranged from between 3 ft 8 ins (1.11 m) and 7 ft (2.13 m). At
Lothal, they were between 6 and 9 ft (1.82 and 2.74 m). The streets, as
evident from the plans, are not constant in their width. For example, one of
the major streets in the lower towns of Kalibangan is about 6.15 m wide at its
northern end, while at the southern end, its width is about 8.20 m. These
variations in width not withstanding, the streets ran remarkably straight.
However, the inner lanes, as the     plans show, seldom ran straight but often
