Problems continue to plague $110 million Riverside Parkway
The city of Grand Junction continues to run into problems with ground settling and cracks developing in a section of Riverside Parkway, a little more than two years after the $110 million bypass was completed.
For the second time in eight months, officials with Centennial-based SEMA Construction have been summoned to make repairs to the parkway bridge over Fifth Street necessitated by subpar work that was done during the construction of the road.
City Engineering Manager Trent Prall said the dirt used to construct the embankment underneath the bridge has settled 4 or 5 inches, causing the road and sidewalk to crack and buckle in several places and water to pool along the shoulder of the westbound lanes of the bridge.
Workers with Mays Concrete, a subcontractor that installed most of the original concrete in the parkway, replaced sections of the road in April and joint sealings that failed near West Avenue. But cracks have appeared again in the bridge, a sign the repair work performed last spring wasn’t sufficient.
“The city had specified for a product, and that product was out of (specification) at some point during the warranty work,” Prall said.
He said SEMA will use high-pressure equipment to inject grout into the embankment to lift it.
He said SEMA performed similar work for the first round of repairs but didn’t lift the embankment enough. This time, the grout will be injected at a deeper level to try to keep the road from settling again.
The work, which will begin Monday and continue through Jan. 14, will result in the closure of one lane of the parkway bridge during off-peak hours, Prall said. Workers will return at a later date to replace the concrete, which will require round-the-clock lane closures.
All of the repair work is covered by the warranty on the parkway, meaning no tax money will be spent. Prall said the parkway had a one-year warranty that extends by another year each time the city notifies SEMA about a project deficiency.
Prall said he doesn’t know the cost of the initial round of repairs or the repairs to be made.
He said the problems with the parkway are unfortunate, but he credited SEMA for making the repairs and not fighting with the city over them.
A call to SEMA for comment Tuesday was not returned.
