This is what I do with Postgis:
select distinct a from
(select the_geom as a from calles_mvd where nombre='TRABAJO') as uno,
(select the_geom as b from calles_mvd where nombre='LIBERTAD') as dos
where distance(a,b)< 0.0001;
That give me the segment of the firs street that hit the second, good to
zoom center in it with some buffer.
