I've also been trying to get bridges drawn on my maps, but they are not
working in MapSource (look fine in gps). I have used both overlays and
continue approaches, but none of them gives good result in MapSource
(6.13.7). I've been comparing my maps with openmtb-spain map
(thines.typ) from Felix, which shows nice bridges in MapSource and I
have almost the same definition for bridges on typ file, i.e. color mode
6-1 common color (line only or transparent bitmap), rendering of slanted
lines skewing, extended labels, no custom colors, no label (invisible).
The only differences are bitmap height and line color, which I think
should not have any effect on the matter. Also Charlie's TYP file has
similar bridges definition.
For the overlays, lines styles file used has the following rules:
(bridge=yes | bridge=true) & highway=motorway [0x121 road_class=4
road_speed=6 resolution 12]
(bridge=yes | bridge=true) & highway=trunk [0x122 road_class=3
road_speed=5 resolution 16]
(bridge=yes | bridge=true) & highway=primary [0x123 road_class=3
road_speed=5 resolution 18]
(bridge=yes | bridge=true) & highway=secondary [0x124 road_class=2
road_speed=4 resolution 20]
(bridge=yes | bridge=true) & highway=tertiary [0x125 road_class=1
road_speed=3 resolution 20]

and the overlays:
0x121: 0x01, 0x2c
0x122: 0x02, 0x2d
0x123: 0x03, 0x2d
0x124: 0x04, 0x2d
0x125: 0x05, 0x2e

For the "continue" approach I've used these rules:
(bridge=yes | bridge=true) & highway=motorway [0x2c resolution 12 continue]
highway=motorway & (maxspeed>129 | maxspeed=none)    [0x01 road_class=4
road_speed=7 resolution 12]
highway=motorway & maxspeed>100                [0x01 road_class=4
road_speed=6 resolution 12]
highway=motorway & maxspeed>80                [0x01 road_class=4
road_speed=5 resolution 12]
highway=motorway & maxspeed>60                [0x01 road_class=3
road_speed=4 resolution 12]
highway=motorway & maxspeed<61                [0x01 road_class=3
road_speed=3 resolution 12]
highway=motorway                    [0x01 road_class=4 road_speed=6
resolution 12]

Have you any clue how to get my bridges drawn in MapSource? What am I
doing wrong?
