Put invisible sprites at each end of the bridge and do this:
//make unhard
sp_hard(&invis_thing, 1);
draw_hard_sprite(&invis_thing);
wait(time);
//make hard
sp_hard(&invis_thing, 0);
draw_hard_sprite(&invis_thing);
//make unhard
sp_hard(&invis_thing, 1);
draw_hard_sprite(&invis_thing);
wait(time);
//make hard
sp_hard(&invis_thing, 0);
draw_hard_sprite(&invis_thing);
