Attentive Source readers know that Harriet the tunnel boring machine has been working her way south under Crenshaw Boulevard, digging the first of twin rail tunnels for the Crenshaw/LAX Line. Today was a good day: the machine broke through into the station box for the Martin Luther King, Jr. Station. Pics above. Please feel free to save and share!
Next stop: Harriet will continue digging toward the future Leimert Park Station.
And here’s a map of the project for those trying to visualize the train’s route:

[…] de esta semana llegó al lugar donde estará la futura estación Martin Luther King, Jr. (aquí foto y video) y luego continuará hacia el sur hasta la futura estación Leimert Park. Se espera que esto ocurra […]

How precisely did the TBM hit its mark? And how precise are the tolerances? Like how displaced off the centerline can it get?
*Beats chest and is making random cave man noises in excitement*
Judging by the pictures…the underground station will have side-platforms instead of center platforms. Correct?
The station will have a center platform.
Are you sure?
Harriet won’t be needed between the Hyde Park and Fairview Heights Stations as this segment will not be, strictly speaking, a tunnel?
Correct. The right of way will be a covered trench performed by cut-and-cover method between Hyde Park and Fairview Heights stations not unlike Expo Line between Jefferson/USC and Expo Park/USC stations.
