* Match elevation to segment being mirrored (may need to cut for elevation changes, watch especially around exits and underpasses/overpasses)
At beginning of the crossover, connect the segment following exit ramp geometry guidance
(10-15 degrees). Consider adding wayfinders to match signage or provide guidance. For example,
* I-80 W only / Thru traffic
* I-80 W / I-480 / SR-14 / All Exits
* Note: be sure to remove alt-names to avoid BC
* Consider that there will likely be a SWL separating lanes before the actual lane crosses over into oncoming lanes.
