It will, the future fast lines though the platforms are attached to the future slow lines just to the east.
It won't change until they get the other platforms sorted and have the 4track alignment to Heaton Lodge sorted.
So the Curve is not as bad as it looks in the picture. The current temporary lines do go over the fast line bridge. Indeed platform 2 is on the bridge.
Sorry for a facebook link, but this video shows the alignment and crossovers at east end of Huddersfield station.
Huddersfield’s Grade I listed station was built in 1847 by architect James Pigott Pritchett, and its six-column portico is considered one of the best in Europe. #trains #huddersfield #sunrise #town...

Shows a 185 leaving platform 3 at Huddersfield eastbound towards Leeds. The train goes over the new bridge on the south side (platform 2 and 3 when done)
After the bridge, the track curves to go into 2 tracks in the middle of the viaduct. There is room for at least 1 extra track on each side.
There are a 2 sets of crossovers, so both ways.
You can see the south side of the Bradford road span is still missing.
The distance is a signalling portal span over al the tracks.
