QUENTINSBURGH- As construction proceeds with construction of the elevated track structure up Apex Drive North and March Point Road about halfway completed, QUARTA has officially changed the final alignment of the QLine Metro local Line 10.
Originally, the line was to proceed up March Point Road all the way to M. Williams Parkway, merging with Line 5 and running out to terminate in Matherspark Village alongside lines 1, 1x, 5, and 5x. However, this was a slight problem. Tracks in the QLine system are only made to support 3 train lines at a time. Line 10 would be the third local line running in the Matherspark Village area, and the tracks technically would have been able to handle it, but local line 1 uses an immense amount of capacity as one of the most used lines in the system, which means some sort of extra tracks after the “merge” may have been necessary to support the additional local line 10.
The primary purpose of the merge with line 5 was to provide a final link back to line 1, as line 10 was built largely to help take some riders off the crowded lines 1 and 14, as well as line 5 which was slowly becoming more crowded.
What QUARTA decided to do instead of the merge with line 5 was to go up March Point Road up until Hinespoint Road and merge with line 11 to run local along Tortoise Ridge Road out to Tortoise Point Towne Center to terminate at Capitol Boulevard with lines 3, 3x, and 11. This realignment connects line 10 with lines 1, 1x, 14 and 14x at Hesperic /Tortoise Ridge, lines 6 at Christian/Tortoise Ridge, lines 2 and 2x at Tortoise Ridge/Bond, and lines 3 and 3x at the terminus, creating far more connections than the original alignment.
The new alignment is also cheaper. By eliminating the 2km bridge between Hinespoint and M. Williams Pkwy, QUARTA saved about f‘150,000,000 on Phase II of Line 10. The new version will be finished by April 2019 in contrast to the mid-2020 originally estimated.
