Causeway Interchange Phase 1 and 2 update

Causeway Interchange Phase 1 and 2 update

POSTED: Tuesday, June 15, 2010 - 11:14am

UPDATED: Tuesday, June 15, 2010 - 2:19pm

The new North Causeway Boulevard to I-10 west on-ramp recently completed over I-10 will soon join the existing on-ramp.

The new I-10 west to North Causeway ramp to the Veterans overpass is progressing north from I-10. The pile driving operation is near completion. The bridge deck is complete to 27th street, just south of Veterans. The removal of the existing bridge rail of the Veterans overpass is underway.

The ground-level portion of the new North Causeway to Veterans off-ramp is complete and the exit to Veterans is open to traffic via a temporary road. The bridge portion of this ramp will begin in a few weeks.

The new I-10 west off-ramp to Southbound Causeway, which was relocated slightly to make room for the other ramps, has been opened to traffic. One more layer of asphalt will be installed on this ramp at a later date.

Work on the new on-ramp from South Causeway to I-10 west is underway south of Veterans. The large foundations adjacent to the service road are being constructed. Once these are complete in early July, installation of the large steel girders spanning Causeway will begin.

Crews have completed the first layer of asphalt of the new ground level on-ramp from Veterans to I-10 west between the service road and I-10. A temporary road is being constructed to connect South Causeway to this ramp. This ramp will open once the existing ramp is closed for construction in July. Construction of the concrete barrier rail is underway.

The construction of drainage structures and water lines along ground-level southbound Causeway Blvd. is also underway.


The North I-10 service road just east of Causeway remains closed at 27th street. A temporary road is being constructed to 26th street such that the service road can be accessed from Southbound Causeway Blvd. via 26th street to Athania Pkwy. This temporary road will be complete next week and open to traffic. This road will be open whenever possible during construction. During certain operations, such as the installation of the steel girders, the service road will be completely closed and traffic will be detoured to Severn Ave. to access the service road.

The U-turn south of Veterans leading to South Causeway is closed. Motorists headed to the I-10 service road should exit at Clearview.

Ground- level North Causeway is reduced to one lane for several months and the U-turn north of Veterans is closed.

The alternate route for I-10 west is to exit at Bonnabel to West Esplanade to Causeway.

The alternate route to Veterans west is instead of continuing on Causeway through Veterans, turn right onto eastbound Veterans and U-turn to go west.

Ground level Southbound Causeway south of Veterans is reduced to one lane. The far right lane of South Causeway between Veterans and I-10 is closed. This is the 3rd lane that serves as the acceleration lane for Veterans entering South Causeway. Veterans traffic should use extreme caution as they yield to enter South Causeway.

There will be frequent daily lane closures on mainline Northbound and Southbound Causeway.

Motorists should expect delays, and we ask that you proceed through the project with caution. Be on the lookout for flaggers and construction traffic entering and exiting the highway, side streets and driveways.

Traffic entering and exiting some streets, driveways, businesses and subdivisions will be temporarily inconvenienced while construction continues. If your business or residence has two entrances/exits, one entrance/exit may be closed temporarily during construction operations, but the other entrance will remain open allowing access to your business or residence. If your business has one entrance/exit, we will maintain traffic in and out of the business or residence while crews work across the driveway.

All above-mentioned work schedules are subject to change due to adverse weather. Please see public notices for exact times, dates and cancellations.
