NAME
   Bridges - Building and destroying bridges

Level: Expert

BRIDGES

Normally bridges can only be built from bridge-heads. (See info Sector-types).
If  the  EASY_BRIDGES  option  is in use, bridges can be built from any sector
that has enough hcm (heavy construction materials)  and  workforce  (see  info
show and the show command), providing you have enough money, and your technol-
ogy level is high enough.

Bridges can only be built over water sectors.

If the EASY_BRIDGES option is in use, you do not need to use  bridgehead  sec-
tors  (although  the  sector  you  build from must still be at least 60% effi-
cient), and the sector the bridge span is to be built in must be  adjacent  to
at  least  1 non-sea, non-bridge span sector. Note that you do not have to OWN
the sector is will be adjacent to, it just has to exist. This means  that  you
can build, for example, a 2 sector bridge out to an unowned island.

To find out the required amounts of materials, workforce, and  money  use  the
show command.

Bridge spans cannot be re-designated.  A bridge span will collapse when it  is
below 20% in efficiency, so shelling will destroy one, as will nuclear weapons
and bombing.

If the EASY_BRIDGES option is NOT in use, a bridge will also collapse  if  its
bridge-head sector goes below 20% or is re-designated.
