Remember that big rock blocking Madison Valley’s big dig? It’s a huge pain — so it’s coming out, Sunday night. Note that the work storm pipeline work crew will also step up the tunnel boring schedule with nighttime work to get back on schedule.
When we last discussed the problem with the Shaft 5 project manager, SPU said the rock could be up to 60 inches wide. It lies in the dirt beneath the pavement in front of Bailey-Boushay House.
Night Work on E Madison Street and Martin Luther King Jr Way ECrews have encountered several large rocks as they tunnel below E Madison Street. While rocks can frequently be removed without the need for excavation, the boring machine has currently encountered a rock that does require excavation from the surface street due to its size and location.
In order to minimize impacts to traffic, crews will excavate and remove the rock this Sunday night, 12/12 (see details below). Crews will also complete tunneling of this segment at night in case additional excavation is required. Any affected surface area will be plated during the daytime to allow traffic to be open in both directions. No daytime construction activities are planned on E Madison Street. (See attached construction flyer for more information).Construction detailsþConstruction hours will be from 6 p.m. to 6 a.m. for the pipeline construction, Sunday evenings through Friday mornings. Other project-related work will continue during daytime construction hours. No work will take place on Friday or Saturday evenings to minimize impacts to businesses.þDuring any potential excavation, uniformed police officers will be onsite to direct vehicles.þSome street parking may be temporarily unavailable to accommodate this work. “No Parking” signs will be clearly posted.þIncreased noise, dust and vibration can be expected, especially during the excavation.þIncreased lighting from the construction work area and construction vehicles.Additional construction updateDaytime work is also planned this Saturday, 12/11, near Shaft 4 (Martin Luther King Jr Way E and E Arthur Place).
