Roads & Transportation

In Mt. Lebanon, we have two types of road construction: Utility-related road repair, which happens when the gas, electric or water company dig into a street to make a repair. Most unplanned road repairs are this type. The municipality does not have control over when and where this type of repair happens. Sometimes, we are not even notified. If we are notified, we will place it on this page, under utility-related road repair.

We also have road surfacing and construction, which is part of the yearly municipal road improvement contract. We will always contact affected residents about this type of repair. We also will post it here every construction season so all drivers can become aware of it.

Where will I find road construction delays in Mt. Lebanon?

What streets are Mt. Lebanon reconstructing this year?

Learn how streets are selected for our municipal road improvement program on our Road Work 101 page.

The 2026 summer reconstruction program is complete for the year. The roads that were completed, as approved by the Commission:

View an Interactive Road Project Map  to view streets reconstructed in 2026. View the reconstruction schedule.

Steps 1-2 from the linked Road Work page will be completed on all streets prior to Steps 3-6 being completed. Therefore there will be some time after work has started on your street when no one will be working, because they are completing work on the other streets.

The program is generally scheduled to begin in May and rebuilding your street will create some temporary inconvenience. We appreciate your patience as we work to complete a major project that will enhance our community and help ensure your street lasts for another 30 years. Unlike periodic patching and resurfacing, street reconstruction involves removing the old base, replacing deteriorated curb and installing new subsurface drainage before applying a new surface.

During the phases of reconstruction, you will not be able to park on your street. When you cannot use your street or driveway, you may park during the day and overnight on nearby streets where it is legal. You do not have to contact the police department. The municipality will notify the police department for you. Please be conscious of other residents when you are parking on the streets. Do not block driveways and be aware of residents’ need to have ample room to back out of their driveways when parking on the streets. The contractor will leave a notice at your front door a few days before construction begins.

Emergency fire, police and medical rescue service will continue as usual, and regular garbage pickup and mail delivery will be maintained. If your street is closed and you need to pick up or drop off a person with a disability or a medical condition, please talk with the Contractor’s foreman. If necessary, he can arrange to have that person transported out of the construction area.

If you are planning to move or are expecting a large delivery during the process, please notify the municipal engineer at (412) 409-2398 as soon as possible. Arrangements will be made if possible; however, you may need to modify your schedule. If you have an irrigation system or an invisible dog fence please let the Contractor’s foreman know prior to the start of construction. These systems are not marked on the surface so there is the potential for accidental removal by the contractor.

What streets are Mt. Lebanon resurfacing this year?

Here are the streets approved by the Commission for the 2026 summer resurfacing program:

View an Interactive Road Project Map  to view streets to be resurfaced in 2026. View the resurfacing schedule .

Construction schedules may need to be revised during the project due to unforeseen issues, such as utility service conflicts. Also the schedule may be affected by poor weather conditions.

How does Mt. Lebanon preserve its brick streets?

Mt. Lebanon’s Historic Brick Streets are cherished parts of our neighborhood character. As such, the Mt. Lebanon Commission passed a brick streets policy in 2023 to help ensure the continuity of key brick roads. Read the policy here.

Each year, the municipality budgets money to repair sections of our brick streets. Because the work is variable, the list is not final until the project is complete each year, based on the amount of damage and time and materials needed to do the repairs within budget.
