Unlocking Road Capacity on Existing Corridors

As traffic volumes grow year-on-year, the pressure on existing road networks intensifies. Road widening and upgradation projects represent a cost-effective strategy for increasing capacity, improving safety standards, and extending pavement life without the full cost of constructing a new alignment.

HRP Infra manages the full project cycle — from traffic census and pavement condition surveys through geometric realignment, land acquisition support, utility shifting coordination, and construction supervision — ensuring that upgrades are delivered on time, within budget, and to the highest technical standards.

Core Capabilities

Our Widening & Upgradation Expertise

Specialised consultancy services across every technical discipline involved in road expansion projects.

Traffic & Demand Studies

Axle load surveys, annual average daily traffic (AADT) analysis, and design traffic computation for a 20-year planning horizon using IRC:37 norms.

Geometric Realignment

Horizontal and vertical curve redesign, superelevation correction, sight distance improvement, and median design to meet IRC:73 and IRC:86 standards.

Pavement Rehabilitation

FWD-based structural evaluation, Benkelman Beam deflection studies, and overlay design including cold milling, crack sealing, and asphalt mix selection.

Land Acquisition Support

RoW strip mapping using DGPS survey, structure inventory, encroachment identification, and land acquisition plan preparation under LARR Act, 2013.

Road Safety Audit

Stage-wise safety audits, black spot identification, iRAP-based risk scoring, and treatment recommendations to reduce crash severity and frequency.

Utility & Drainage Design

Identification and shifting plan for OHE, underground utilities, and telecom cables; updated drainage design to match widened carriageway conditions.

Technical Approach

Data-Driven Engineering Decisions

Every widening project begins with a thorough existing-conditions assessment. We combine ground-truth surveys with satellite imagery and GIS analysis to build a complete picture of the corridor before a single design line is drawn.

  • Pavement Condition Index (PCI) SurveysDistress mapping across the full corridor to identify priority rehabilitation zones.
  • LiDAR & DGPS SurveysHigh-accuracy terrain and cross-section data reducing design errors and rework.
  • Social Impact AssessmentStructure inventory, affected family census, and R&R plan as per government policy.
  • Value Engineering ReviewsAlternative design scenarios evaluated for cost, environmental impact, and constructability.
