Road Projects Around St. Luke’s Boise Advance 

April 18, 2018

St. Luke’s patients and staff, along with drivers and pedestrians in the Fort Boise area, will see construction activity stretching around the downtown Boise hospital campus.

Here are the latest updates:

Road-construction crews have made significant progress on the major transportation and utility improvements taking place around St. Luke's hospital in downtown Boise.

Aging water, sanitary sewer and storm sewer pipes serving the hospital and surrounding neighborhoods have been replaced, and much of the road work is fairly far along.

The transportation projects are being done in partnership with ACHD and the City of Boise.

Here are the latest developments:

Main patient/visitor parking garage in Boise 

  • To park at the Boise hospital, patients and visitors should use Idaho Street. The entrance off Avenue B at Bannock Street is under construction. 
  • Whenever possible, one lane in to the hospital at Avenue B will remain open for Emergency Department access. Any complete closures of the Avenue B entrance will occur during off-hours, with a guide in place to redirect emergency patients to Idaho Street via a U-turn.

Jefferson Street behind the Boise hospital

  • Jefferson Street at Avenue B through 1st Street is temporarily closed to through traffic. Local and business traffic will be allowed. This is the street directly behind the main Boise hospital. During this time, pedestrian traffic will be allowed on the north side of Jefferson Street.  After the sidewalk and pedestrian ramps are constructed on the south side of Jefferson, between Jefferson and Bannock, pedestrian traffic will be moved to that side of Jefferson, and sidewalks will be constructed along the north side of Jefferson Street.

The above closures, which will last several weeks, will allow crews to make progress on the cycle track and do work for other projects, including electrical boring for the new Idaho Elks Children’s Pavilion.

State Street between 1st Street and 3rd Street

  • State Street between 1st Street and 3rd Street is open to westbound traffic only. 
  • Eastbound traffic should use West Fort or Main streets. 
  • Eastbound travel is allowed only for business access on State Street between 2nd and 3rd streets. 

1st Street closures

  • 1st Street also is closed between Jefferson and State streets for roadwork as well as to improve traffic flow. The closure allows traffic to move much more efficiently along the State Street/Fort Street corridor as cars aren't exiting and entering 1st Street. 
  • Vehicle access to Family Medicine Residency of Idaho (FMRI) and the St. Luke's Physical Plant is through the parking lot off of Jefferson Street near Avenue B. 

Sidewalk closures, lane reduction on Avenue B

  • The sidewalk on the west side of Avenue B, between Warm Springs and Bannock streets, is closed.
  • The sidewalk on the west side of Avenue B, between Bannock and Jefferson streets, is also closed.
  • The westernmost southbound traffic lane of Avenue B is closed between Warm Springs Avenue and Bannock Street. (There is still southbound access as one lane remains open in each direction.)

Avenue C closed through 2018

  • Avenue C between Jefferson and Bannock streets is closed so that construction can proceed on the Idaho Elk's Children Pavilion. 
  • Jefferson Street between Avenue B and Avenue C is open.

Reserve Street and the Reserve Street roundabout

  • Reserve Street and the Reserve Street roundabout are fully operational. This includes left-turn access. 

Idaho Street

  • Idaho Street is one lane in the area around the downtown Boise hospital so crews can continue to work on projects.

Pedestrian access

  • Pedestrians should be on the lookout for construction signage detailing the latest detours as they navigate the downtown campus and the areas around St. Luke's Rehabilitation. 


St. Luke’s Health System, in conjunction with ACHD and the City of Boise, started road construction in July around St. Luke's downtown Boise hospital. This work is in preparation for the development project that will modernize the Boise hospital in order to improve access and care, while providing improved transportation flow. 

The first phase of work centered on improvements to public roads and infrastructure in a 12-block area around the hospital. The goal is to better link the area with Boise’s downtown urban core. 

Major aspects of this phase include:

  • Construction of the new roundabout at the intersection of East Fort and Reserve streets.
  • Construction of a dedicated cycle track around the St. Luke’s perimeter.
  • Realignment and improvements on the intersection of 1st, Fort and State streets.
  • Creating a dedicated right turn from north-bound Avenue B on to East Jefferson.
  • Installing bigger sidewalks and bike lanes around the campus perimeter where space allows.

During this work, road construction crews will be concentrated:

  • Throughout Avenue B, East Fort, West Fort, State and Reserve streets.
  • Additional crews will be working on Idaho and 2nd streets. 

Old and New Routes

Drivers are also encouraged to reduce speeds in the hospital area because of the activity. Construction crews urge travelers to please be attentive while driving through the project area as conditions change regularly.  Drivers are reminded that they present an additional hazard to work crews. 

They’re urged to do their part to create a safe work environment to the men and women working to improve area roads.  Travelers are also encouraged to add a few extra minutes to their commutes or find alternative and detour routes to avoid delays.

Improvements along the perimeter of the campus include constructing the cycle track, curbs, gutters and sidewalks.


While the work is going on, no parking will be allowed on Idaho Street in the hospital corridor.

Hospital visitors, patients, physicians and staff that use the South Tower parking garage should add a few extra minutes to their trip because of construction delays.


For patients receiving care at MSTI, please note a drop-off area will remain accessible throughout construction. If other instructions are necessary, signs will be posted to help guide drivers.

Anderson Plaza

Patients visiting the Anderson Plaza building on 2nd Street should be aware that the main front entrance may be impacted by construction of the cycle track.

Tree removal

Due to the sidewalk and cycle track improvements and as considered at public hearings, trees in this area were removed. St. Luke’s is contractually obligated to replace removed trees using the city forester’s valuation and ACHD right-of-way rules. The tree removal is the result of three specific transportation projects the City of Boise, ACHD and the community requested of St. Luke’s:

  • Increased intersection capacity.
  • City Modal Elements: the cycle track and other amenities requested by the city.
  • Fort Boise Master Plan – Reserve and Fort / Fort and Robbins roundabouts.

St. Luke’s is working closely with the city forester to plant 90 new trees in the cycle track median, in exchange for the 64 removed. St. Luke’s will ensure sensitive and appropriate choices are made for the restoration of the tree canopy throughout this portion of the plan. St. Luke’s intends to plant trees that are more valuable than required under city code and has agreed to incur this expense, even though the work requiring the majority of removals is directed by the three-party agreement.

Road work in this area will last at least through early next year, depending on the weather. Because of the fluid nature of this type of project, timelines will be adjusted. When changes impact drivers, pedestrians, cyclists, patients, staff and the neighborhoods, St. Luke’s will communicate the information in a timely manner.

Main Boise campus

The work is part of St. Luke’s Master Plan for its Boise campus and is the result of years of extensive study, planning and collaboration with key stakeholders, including the City of Boise, the Ada County Highway District and area residents. The thorough process included dozens of workshops, open houses and neighborhood association meetings, which helped to shape and evolve the plan through thoughtful input.

This is not a “single project,” but a multi-phased plan that will occur in stages over the years to come. At its core is our commitment to create an environment in which we can provide the best possible care for patients and families, in an environment geared toward safety, healing and comfort, explained Dave McFadyen, St. Luke's Boise administrator.

“We are happy this is finally moving forward because this development allows us to better meet the needs of our patients by providing modern, advanced care in a more user-friendly setting,” said McFadyen.  “While this development does add capacity, it's less about growth and more about re-configuring our campus.  It will be easier to navigate and find your doctor.  There’s more room to care for our growing, aging community struggling with more complex chronic health problems.  Our physicians will be right there ready to help in an emergency rather than a few blocks away, and our facility will be upgraded in a way that it flows better, saving precious minutes in emergencies, when time truly matters.”


  • New Children’s Pavilion (under construction)
  • New central plant
  • New parking structure
  • New hospital tower
  • Expand and modernize St. Luke’s MSTI cancer center
  • Expand and modernize St. Luke’s Children’s Hospital
  • Expand and upgrade the current hospital tower

Together, the project will be one of the largest investments ever made in Boise and Idaho. It will bring new jobs to the region while building on Boise’s growing reputation as one of the most livable cities in the country with the high-quality health care that is a critical component of quality of life. The project will be financed through bonds, cash on hand and community philanthropy. This major development project is estimated to bring as much as $1.2 billion of rollover economic benefit and job growth to the community.
