Track work on a busy rail line will hamper traffic at a busy Independence intersection.

The Union Pacific is doing $5 million in maintenance work in the area. On the weekend of Oct. 8-9, that will mean closing the crossing at 35th Street, just west of Noland Road, for up to 36 hours.

The street will be closed at that crossing at 7 a.m. Oct. 8, a Saturday. The crossing will open sometime Sunday, and that’s expected to be before 7 p.m.

Residents and business owners in the area can call Donna Coatsworth, city transportation engineer, at 816-325-7608 for more information.

This comes toward the end of about three weeks of work the railroad is doing on its 35 miles of track from Independence to Pleasant Hill. That work has briefly closed other road crossings in the city as well. Overall, the railroad is doing work at 44 road crossings.

It’s also forced Amtrak to alter its daily schedule, chiefly by delaying the afternoon training coming from St. Louis and the evening train that goes back to St. Louis. Also, starting Saturday, the morning train out of Kansas City will run an hour and 15 minutes, departing Kansas City at 7 a.m. and stopping in Independence at 7:19 on its way to St. Louis. That lasts through Oct. 8. On Oct. 9, when Amtrak reverts to its normal schedule for all four cross-state trains.

The maintenance work includes replacing 21,800 ties, replacing more than a mile of rail at various curves and laying down 16,000 tons of rock on the roadbed.
