Gas House Pike Bridge Replacement


Project Overview


This federally funded Capital Improvement Program (CIP) project is for improvements to Gas House Pike at Linganore Creek for the replacement of two existing structures, a larger multi-cell structure known as Gas House Pike Bridge (Structure No. F09-21) and a nearby smaller multi-cell pipe structure just west of Gas House Pike Bridge, which will become a new bridge (Structure No. F09-25). The proposed project work will include complete removal of both existing structures, installing a single 77' span prestressed girder bridge with concrete substructure and caisson foundation, installing a single 52' span prestressed girder bridge with concrete substructure and caisson foundation, installing new bridge parapets, replacing portions of the existing traffic barriers, installing new traffic barriers and end treatments, installing pipe culverts and headwall, installing storm water management facilities, installing roadway drainage improvements, installing a 10" diameter sanitary sewer line with associated items (Add-Alternate No. 1), 12" diameter water line with associated items (Add-Alternate No. 1), regrading approaches, placing full depth pavement and tying grading into existing topography, milling, patching, and surface paving along Gas House Pike from Sta. 98+40+/-, extending west for approximately 1.7 miles, to existing paved intersection of Boyers Mill Road/McKaig Road/Gas House Pike (Add-Alternate No. 2), and installing a formliner finish on the concrete parapets of the bridges' superstructures (Add-Alternate No. 3). The bridge structures and roadway approaches will have two 11-foot lanes with 5-foot shoulders to meet collector standards. The CIP project will provide needed safety improvements and reduce the frequency of flooding at this location.

Current Status


The project re-advertised on January 14, 2020 as Bid No. 20-283-CP and Bid Opening occurred on February 20, 2020. On October 2, 2020, the contract was awarded to W.F. Delauter & Son, Inc. in the total contract amount of $3,654,032.89.

A Pre-Construction Meeting with the County and Contractor was held on October 15, 2020.  

A full-time road closure for the majority of construction duration and completion of the project is required. Per the project contract, the duration for project completion is 430 calendar days (CD). However, there is an incentive/disincentive special provision to open the road to traffic by the 360th calendar day. Unforeseen revisions required to the superstructure and unforeseen delays due to a September 22-23, 2021 storm event caused construction delays to the critical path work items affecting the incentive time to open the road to traffic, an additional 16 CDs have been added to the incentive time. The County approved and revised (via change order) the incentive time in the contract from 360 CD to 376 CD. Therefore, the full-time road closure is anticipated to be in effect for 376 calendar days. Please note, the road will NOT be closed for the full contract duration of 430 calendar days. The updated project schedule/timeline (pending weather/unforeseen circumstances) is as follows:

  • Construction Notice-to-Proceed: November 30, 2020
  • Road Opening to Traffic at Calendar Day 376 (Incentive Date): December 10, 2021* (Revised)
  • Completion Date at Calendar Day 430: February 2, 2022**

UPDATES:  *Gas House Pike at the bridge over Linganore Creek is now RE-OPENED, as of December 15,  2021. County public notification on the re-opening of Gas House Pike was sent out to the general public and agencies (see Public Notifications and Notices below).  

                **The bridge project still has some remaining work for the completion of the project and it required design revisions due to an unforeseen storm event. Additional work and additional time will be needed t​o complete remaining work and revisions. This remaining work is to be done near and/or off the roadway and may require a one-lane closure, utilizing a flagging operation at times (but the road will be open to traffic).



Notification of the bridge closure was sent via public notification and a resident Newsletter was mailed to area residents (see Public Notifications and Notices section below for both notices). Gas House House Pike at the Bridge over Linganore Creek was closed on December 7, 2020. A signed detour is now in effect and will utilize McKaig Road, Old Annapolis Road, Green Valley Road (MD 75), Drummine Road, Central Church Road, and Gas House Pike. Construction completion is estimated for early spring 2022, pending unforeseen weather or unforeseen conditions.

Construction Field Photographs

07-07-21 F0925 Beams Installed (Looking east)

Prestressed Concrete Beams (total of 5, approx. 53.5 ft. long each) were installed for the small bridge (Structure No. F09-25) on July 7, 2021 (looking east along Gas House Pike across F09-25).

All 5 prestressed concrete beams (July 7, 2021 installed) for Structure No. F09-25. Looking northeast under structure at existing ground level.  

09-08-21_F0925 Deck_Placing Concrete

Superstructure reinforcement steel was completed for Structure No. F09-25 and concrete deck placement occurred on September 8, 2021.  Concrete pumping truck placed concrete for the superstructure deck.  Bidwell machine (in background) is finishing the placed concrete to meet designed deck elevations.

Screed on the Bidwell machine is bringing the placed concrete to finished elevation on the bridge deck for Structure No. F09-25 (performed on September 8, 2021).

Beam #5, the last of 5 prestressed concrete beams, was installed for the large bridge (Structure No. F09-21) on August 2, 2021 (looking northeast along Gas House Pike at the west abutment side).

GHPB_Parapet Aesthetics (Formliner Finish)

Aesthetics on the bridge parapets were part of the design. Photograph is of the completed stained, formliner finish on Structure No. F09-25 (52-foot span, smaller bridge).  A formliner pattern was used during concrete parapet installation on both bridges to simulate large, river rocks as the concrete finish.

GHPB_Ready to Open to Traffic

Photograph is of the completion of two new bridges, Structures Nos. F09-25 and F09-21, new roadway approaches and roadway tie-in sections, just prior to the re-opening of the road on December 15, 2021. Roadway pavement markings and required guardrail were also necessary to be installed before the road re-opened to traffic.
